The Top 20 and some deltas
by Tony Bates 14 Sep '94

14 Sep '94

This is an auto-generated mail on Wed Sep 14 21:10:00 MET DST 1994 As stated above this is auto-generated so it is not checked before it leaves my workstation. This is a list of the "Top 20" players who if CIDRizing at the AS level could make a significant gain in the size of Internet routing tables. This may be an over-estimation but it is hoped that this can act as an incentive for the "Top 20" and others to look at their CIDR capability. This report is available as: ftp://ftp.ripe.net/cidr/stats/Top-20.14Sep94 The current (and of course this one today) report is always accessible as: ftp://ftp.ripe.net/cidr/stats/Top-20 A full summary of all the ASes seen in the Internet can be seen by looking in: ftp://ftp.ripe.net/cidr/stats/AS* Please also find a summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does some indication of ASes participating in CIDR. More information can be found in: ftp://ftp.ripe.net/cidr/stats/Delta.* Also, for a short time this gives details of any possibly interesting aggregates currently seen in the routing. Interesting here means not a aggregate made as a set of classful routes. This a daily snapshot of changes in classfull routes being withdrawn and added. the deltas are calculated over a rolling 7 day period. Please bear in mind this is purely a "snapshot" and a large flucuation could be caused by a connectivity problem for example. However, this does give some indication of service providers that are moving to classless routing.

Draft Transition document
by Tony Bates 08 Sep '94

08 Sep '94

Find below the draft of the promised transtition document to incorporate all the proposed features of the new database. This is also available as ftp://ftp.ripe.net/ripe/drafts/db-trans.{txt,ps} We will bring copies of this document to the RIPE as we are so late in getting it out (we will not be doing this for other documents so please take note). Regards and see you in Lisbon, --Tony. RIPE Database Transition Plan DRAFT DRAFT DRAFT Tony Bates Daniel Karrenberg Marten Terpstra Document-ID: ripe-1nn August, 1994 ABSTRACT This paper details a transition plan of the changes needed to move from the current RIPE Database to a RIPE Database that supports classless IP network numbers, authorisation of updates and changes to Routing Registry information. 1. Introduction The RIPE database is about to undergo some major changes. These changes come from a set of documents produced by various RIPE work- ing groups and the RIPE NCC. There are three major changes to the RIPE database that will affect the database in such a way, that a description of the changes and a clear transition plan is needed. These three changes are: o Support for Classless Internet Addresses [1]. o Authorisation and Notification of Changes [2]. o Representation of IP Routing Policies in a Routing Registry [3]. All these three new features of the RIPE database will affect the working of the RIPE Database, from simple things like altered out- put, to more complex things like guarded attributes and objects [4]. The three changes will be dealt with in turn in this document. If you wish to get a quick overview of how this affects you please refer to Section 5. ripe-1nn.txt August, 1994 - 2 - Each of the sections will have points in time attached to them, at which time a certain change will take effect. These points in time are labeled T1 and T2. For some changes that need to be made, a cer- tain "flag day" is needed. On these days some changes will take place that are not backward compatible and must be performed in a "big bang" type of change. These dates are labeled B1 and B2. All changes will be labeled with a Tn and/or a Bn. Table 1 shows the current time estimates for each of these changes. +---------+----------+------+ | Date | Big Bang | Time | +---------+----------+------+ | Now | | T0 | |15-10-94 | B1 | T1 | | 1-12-94 | B2 | T2 | +---------+----------+------+ Table 1: Timescales for transition changes In the sections describing a change, there will be a small section shortly describing the effect this will have on users of the RIPE database. For this document the users have been categorised in four groups: users querying the database, AS and community guardians, maintainers of "inetnum" objects and maintainers of other database information. 2. Support for Classless Internet Addresses There are several aspects pertaining to the introduction of class- less Internet addresses in the RIPE Database as document in [2]. 2.1. Querying the RIPE database To support classless addresses in the RIPE database, one different representation of Internet addresses will be supported for queries to the database. This notation is the prefix/length notation as explained in [1]. Correct queries to the database will be for exam- ple: 192.87.45.0/24 192.87.228.0/23 128.141.0.0/16 193.0.0.132/32 For backward compatibility, "old" style queries will still be sup- ported. They are however internally to the database server trans- formed to a prefix/length notation, after which they are handled as above. This transformation could change the expected output. For example: ripe-1nn.txt August, 1994 - 3 - 192.87.45 will be rewritten internally to 192.87.45.0/32 128.141 will be rewritten to 128.141.0.0/32 193.0.0.0 will be rewritten to 193.0.0.0/32 Other type queries that are supported, but not encouraged are pre- fix/length queries, for which the prefix is not a full dotted quad: 128.141/16 will be rewritten to 128.141.0.0/16 192.87.45/24 will be rewritten to 192.87.45.0/24 For queries where the prefix and the length are incompatible (like 192.87.45.0/8), the length will be used to mask off all extra bits from the prefix. This example will be rewritten to 192.0.0.0/8. % whois -r 193.1.209.0/24 inetnum: 193.1.209.0 netname: NCIR-LAN descr: Local Ethernet descr: National College of Industrial Relations descr: Sandford Road descr: Dublin 6 descr: Ireland country: IE admin-c: Neil Armstrong tech-c: Neil Armstrong connect: RIPE NSF aut-sys: AS1213 changed: mnorris(a)hea.ie 940823 source: RIPE % whois -r 193.1.209.0/8 inetnum: 193.0.0.0 - 193.255.255.255 netname: RIPE-CBLK descr: European Address Block #1 country: EU admin-c: DK58 tech-c: TB230 tech-c: MT2 remarks: delegated changed: testdb(a)ripe.net 940707 source: RIPE The default behavior for the RIPE database will be to respond to the query with an exact match if possible, or otherwise the first less specific match it can find. In most cases this will mean that when queries for host addresses (193.0.0.132/32) one will receive the network block this host is part of as registered in the database (in this case probably 193.0.0.0/24). ripe-1nn.txt August, 1994 - 4 - % whois -r 193.0.0.132/32 inetnum: 193.0.0.0 netname: RIPE-NCC descr: RIPE Network Coordination Centre descr: Amsterdam, Netherlands country: NL admin-c: Daniel Karrenberg tech-c: Marten Terpstra tech-c: Tony Bates aut-sys: AS3333 ias-int: 193.0.0.221 AS1104 ias-int: 193.0.0.157 AS1104 rev-srv: ns.ripe.net rev-srv: ns.eu.net notify: ops(a)ripe.net changed: tony(a)ripe.net 940708 source: RIPE The RIPE NCC will also insert objects that describe a block delega- tion to an Internet Registry into the database. For example the block 193.1.0.0 - 193.1.255.255 delegated to HEANET, will have an associated entry in the database. When one would query a network number from this block that has not been allocated by HEANET yet, the server will respond with the object for the complete block. This means that less queries will result in a "No entries found" answer, but will give some indication of where that specific piece of address space currently resides. The same is true for address blocks 193.0.0.0 - 193.255.255.255 and 194.0.0.0 - 194.255.255.255 dele- gated to the RIPE NCC. % whois -r 193.1.141.0/24 inetnum: 193.1.0.0 - 193.1.255.255 netname: EU-BLOCK-193-1 descr: HEAnet country: IE admin-c: Mike Norris tech-c: Mike Norris remarks: delegated changed: marten(a)ripe.net 930901 source: RIPE The database server will also support some extra features to display the complete list of less specific matches, a list of direct more specific matches, and a list of more specific matches including more specifics of more specifics. The flags to enable these features can be found in the RIPE whois client manual page. All of these changes will take place at once when enabling the soft- ware that supports classless internet addresses at B1. Changes to tools that make use of the database server have to be made before ripe-1nn.txt August, 1994 - 5 - that time. 2.2. Changes to the guardian files Currently all guardians of guarded attributes maintain files on the RIPE NCC database machine. These files are examined once per day and the associated guarded attribute added to all network objects listed in these files. When a network block is found in the database , and not all of the networks in this block are mentioned in a guardian file, this block is split so that only the mentioned networks get the associated guarded attribute. This procedure can no longer work in a classless database for two reasons: o from a block of network numbers it is no longer clear where one network ends and the next one starts. The class A, B and C boundaries no longer apply, so the software cannot make deci- sions any longer on where to split a block if necessary; o a certain network number can appear more than once in the database in different block entries. In normal cases, any net- work number assigned through the NCC will appear at least three times in the database: once in the entry describing the alloca- tion to an end-side or user, once as a block delegation from the NCC to a local registry, and once as a block delegation from IANA to the RIPE NCC. It is therefore impossible for the software to find out which of these blocks should be split and where this guarded attribute should be added. The way this will be solved is to only add guarded attributes to objects if the entry in the guardian file exactly matches the "inet- num" value of an object in the database. Assume we have a guardian file that contains two lines: 192.87.45.0 193.0.0.0 - 193.0.0.5 In this case, the guarded attribute associated with this file will NOT be added to entry "192.87.45.0 - 192.87.46.0", "193.0.0.0 - 193.255.255.0" or any other non-exact match in the database. Since blocks are no longer split, any line in the guardian file that does not correspond to an exact match in the database, will cause a notification mail message to be sent to the guardian with the expla- nation that no match could be found in the database. Because this is a direct effect of the enabling of the classless ripe-1nn.txt August, 1994 - 6 - software, this change will have to be made at B1. This means that all guardians will have to check their files for non-matching entries and correct them. The NCC will assist all guardians that have an account on the NCC database machine by generating a problem file for them. This file will list all entries in their guardian file that are either not present in the database, or entries that are appear in a bigger block in the database. Any non-exact match can therefore easily be spotted. The program producing these files will run every night up till B1. The file generated will be called "problems" and will be put in the home directory of each of the guardians. Guardians are strongly requested to change their guardian files to eliminate any non-exact match before B1. At point B1, non-exact matches can cause a loss of guarded attributes. It should be noted that this transition is an interim measure to be used between T1 and T2. A completely new procedure to guard attributes and objects is outlined in [2] and a transition for that proposal is outlined in the next section. 3. Authorisation and Notification of Changes The RIPE NCC has produced a paper that describes a mechanism to authorise and notify any changes to objects in the RIPE database [2]. Although these changes apply to all objects in the database, there are some transition issues when these mechanisms are used to replace the current guarded attribute and guarded object procedure. The general use of the authentication and notification will be available from T1. 3.1. Guarded Attributes As explained in [4] the current procedure for guarded attributes is that guardians maintain files on the NCC database machine, from which guarded attributes are added to objects to the database. Although this has worked reasonably well for over a year, it can be solved with a more general authentication and notification scheme. This scheme is explained in [2]. The introduction of "route" objects in the RIPE database (see below) removes the necessity of guarded attributes in their current form. The primary reason for having guarded attributes (authenticity guar- antees because of their operational impact) can be solved by the general authentication scheme. The transition issues involved are of a bootstrap nature. This tran- sition plan foresees the generation of routes from existing network numbers. This will be explained in more detail in the next section. When these newly generated routes are to be used they should be properly maintained using the proposed mechanism. To bootstrap this procedure and to ensure that all routes are properly maintained, the NCC will generate an example "mntner" object [2] for all guardians ripe-1nn.txt August, 1994 - 7 - that have an account on the NCC database machine. The information for this object will be placed in a file in each guardian's home directory. The file name will be "mntner". The information in this object will be derived as best as possible from the current guardian information. These objects will be gener- ated once only. The guardian can then change this object in whatever way he/she wishes. The guardian can even decide to already submit the modified "mntner" object generated for them to the database. At B2, all routes that will be generated from the current network numbers will be maintained by the maintainer mentioned in the file generated in the associated guardian accounts. To ensure that all generated routes are properly maintained, only the "mntner" file in each of the guardian's accounts will be used to tag the newly gener- ated routes. The "mntner" object found in this file will also be automatically entered into the database. Guardians that currently maintain multiple files on multiple accounts can decide to only reg- ister with a single "mntner" object. They will have to ensure that the "mntner" objects in all their accounts are equal. For more details see below. The current guardian procedure will be turned off at B2. At that time, the newly generated route objects should all be maintained, and the need for guardians in the current meaning will have disappeared. All guardian accounts and files will be removed shortly after B2. 3.2. Guarded Objects The RIPE database currently has support for guarded objects. These are objects that cannot be updated using the automatic procedure, but need to be manually checked by NCC staff and are then forwarded to the database. Currently the only guarded objects are "community" and "aut-num". This mechanism was put in place to avoid mistakes when updating operationally critical objects like autonomous system objects. It is fairly obvious that this procedure can be replaced using the authentication mechanism described in [2]. At T1, the maintainer mechanism will be enabled and current guarded attributes can start using this mechanism to replace the manual intervention by the NCC currently needed. For a certain time, guarded objects will still be accepted using the old mechanism (mailed to ripe-dbm(a)ripe.net for checking), but whenever a "mnt-by" attribute is present in any guarded object, these objects can be updated automatically. This does however mean it will have to pass the authorisation as specified by the maintainer. 4. Transition to RIPE-81++ There are several important aspects pertaining to the transition of the objects documented in RIPE-81++ [3]. This also includes the related "inet-rtr" object [5]. ripe-1nn.txt August, 1994 - 8 - 4.1. Separation of routing from allocation information This represents a significant change to both the database objects and to actual data in the database. The two database objects affected will be the existing "inetnum" [8] object and the "route" object as detailed in [3]. This will result in some information being moved from the "inetnum" [6] object to "route" object and some information being deleted from the "inetnum" object. If we look at an existing "inetnum" object: inetnum: 192.87.45.0 netname: RIPE-NCC descr: RIPE Network Coordination Centre descr: Amsterdam, Netherlands country: NL admin-c: Daniel Karrenberg tech-c: Marten Terpstra connect: RIPE NSF WCW aut-sys: AS3333 comm-list: SURFNET ias-int: 192.87.45.80 AS1104 ias-int: 192.87.45.6 AS2122 ias-int: 192.87.45.254 AS2600 rev-srv: ns.ripe.net rev-srv: ns.eu.net notify: ops(a)ripe.net changed: tony(a)ripe.net 940110 source: RIPE The routing information contained in the "inetnum" object will now be distributed over two objects like so: ripe-1nn.txt August, 1994 - 9 - inetnum: 192.87.45.0 netname: RIPE-NCC descr: RIPE Network Coordination Centre descr: Amsterdam, Netherlands country: NL admin-c: Daniel Karrenberg tech-c: Marten Terpstra rev-srv: ns.ripe.net rev-srv: ns.eu.net notify: ops(a)ripe.net changed: tony(a)ripe.net 940110 source: RIPE route: 192.87.45.0/24 descr: RIPE Network Coordination Centre origin: AS3333 comm-list: SURFNET remarks: ias-int: 192.87.45.80 AS1104 remarks: ias-int: 192.87.45.6 AS2122 remarks: ias-int: 192.87.45.254 AS2600 changed: dfk(a)ripe.net 940427 source: RIPE The general idea is all routing based information is moved from attributes within the "inetnum" object to the "route" object (1). It is important to note the direct effect this have on the "inetnum" object data. Table 2 below gives a full list of the transitioned attributes. It should also be noted that in an effort to clean up the "inetnum" object at the same time certain attributes will be obsoleted. The effect column has an T for transitioned and an O for obsoleted. +------------------+--------+-----------------+ |inetnum attribute | effect | route attribute | +------------------+--------+-----------------+ |aut-sys | T | origin | |comm-list | T | comm-list | |ias-int | T | remark | |connect | O | | |gateway | O | | |routpr-l | O | | |bdrygw-l | O | | +------------------+--------+-----------------+ Table 2: Affected attributes As can be seen a simple translation can be made and this will be the _________________________ (1) The "ias-int" attributes are preserved as re- marks. See details of "inet-rtr" object for reasoning behind this. ripe-1nn.txt August, 1994 - 10 - last major transition step at time T2. 4.2. Auto-Generation of "Route" and New "Inetnum" objects Clearly, the transitioning of data will require a major flag day where the translation of attributes detailed in Table 2 takes place. This is expected to occur at big bang B2. At point B2 the RIPE NCC will automatically generate both new "route" and "inetnum" objects in line with Table 2 and load them into the RIPE database. It should be noted that these changes will only take place to "inetnum" objects with have an associated "aut- sys" attribute. All "inetnum" objects not containing the aut-sys attribute will have both T and O attributes removed. This may mean the potential loss of comm-list information if there is no corre- sponding aut-sys attribute for the existing "inetnum" object. Between time T1 and T2 the NCC will generate for each guardian account both the translated "inetnum" and "route" objects in the form of files known as: new.inetnum This file will contain a full list of "to be generated" "inet- num" objects. new.route This file will contain a full list of "to be generate" "route" objects. These files will be re-written every night and are purely given to give each guardian of what will happen to any associated object ref- erencing a guarded attribute after B2. The new "route" objects will be automatically split into CIDR [7] compliant aggregates. Below is a simple example of an automatic object split from the current "inetnum" to a new "inetnum" and "route" object. The original "inetnum" is as follows: inetnum: 193.12.128.0 - 193.12.132.0 netname: SE-COMVIS-NET descr: ComputerVision Sweden AB country: SE admin-c: Anders Andersson tech-c: Anders Andersson connect: SWIP aut-sys: AS1257 changed: uffe(a)swip.net 930707 source: RIPE ripe-1nn.txt August, 1994 - 11 - The will be translated to an new "inetnum" object as follows: inetnum: 193.12.128.0 - 193.12.132.0 netname: SE-COMVIS-NET descr: ComputerVision Sweden AB country: SE admin-c: Anders Andersson tech-c: Anders Andersson changed: uffe(a)swip.net 930707 source: RIPE Notice all attributes noted in Table 2 are now removed. The follow- ing two (yes two, because this entry was not CIDR [7] aligned) "route" objects are also generated: route: 193.12.128.0/22 descr: SE-COMVIS-NET origin: AS1257 mnt-by: AS1257-MNT changed: ripe-dbm(a)ripe.net 940829 source: RIPE route: 193.12.132.0/24 descr: SE-COMVIS-NET origin: AS1257 mnt-by: AS1257-MNT changed: ripe-dbm(a)ripe.net 940829 source: RIPE You also see that mnt-by attributes have been added to the "route" objects. This information has been derived from the "maintainer" files in each guardian account (see above for details of this). In this case the guardian of AS1257 named his maintainer object "AS1257-MNT". All other administrative attributes are preserved in both the "inetnum" and "route" objects which exception of the changed field which in the "route" object will just represent the At the time B2, you will also see both the new "inetnum" and "route" objects in the database. If "inetnum" entries are sent into the database with obsoleted attributes the entries will be accepted with the obsoleted attributes removed and a warning sent back indicating the obsoleted attributes have been removed. The auto-generation will happen at a set time at B2. This is a one- time operation and all users of the RIPE database should be aware of this major change. ripe-1nn.txt August, 1994 - 12 - 4.3. The "inet-rtr" object The "inet-rtr" object is an object which can be used to describe any router within an autonomous system [5]. This object can be used as of time T1. One important piece of the "inet-rtr" object is that it will replace the "ias-int" attribute used in the old "inetnum" object. We encourage all users of the "ias-int" attribute to regis- ter new "inet-rtr" object from time T1 onwards. In an effort to pre- serve any loss of "ias-int" information when the auto-generation of "route"'s and "inetnum"'s takes place the ias-int information will be included as a "remarks" attribute in the generated "route" object. Here is a simple example: route: 192.87.4.0/24 descr: EUR-IP origin: AS1755 remarks: ias-int: 192.87.4.17 AS1755 remarks: ias-int: 192.87.4.18 AS1103 remarks: ias-int: 192.87.4.19 AS2121 remarks: ias-int: 192.87.4.20 AS286 remarks: ias-int: 192.87.4.21 AS1104 remarks: ias-int: 192.87.4.22 AS1755 remarks: ias-int: 192.87.4.24 AS1103 remarks: ias-int: 192.87.4.35 AS1128 remarks: ias-int: 192.87.4.27 AS1890 remarks: ias-int: 192.87.4.28 AS3333 changed: ripe-dbm(a)ripe.net 940829 source: RIPE We realise this is non optimal and encourage the use of the "inet- rtr" object from time T1 onwards. 4.4. New "RIPE-81++" Syntax All proposed "ripe-81++" syntax will be accepted after B1 at time T1, with the exception of the changes to "inetnum" and "route" objects which will not be accepted until B2 at time T2 (see section "Auto-Generation of "Route" and New "Inetnum" objects" above for reasoning behind this). The direct effect of this is you will see different whois output. The most important aspect will be the addi- tion of syntactic sugar to the existing "as-in" and "as-out" attributes as well as the ability to use the attributes as well. To highlight this change if we look at a current "aut-num" object a whois query would produce the following: ripe-1nn.txt August, 1994 - 13 - aut-num: AS1104 descr: NIKHEF-H descr: Science Park Watergraafsmeer descr: Amsterdam, The Netherlands as-in: AS1103 100 AS1103 as-in: AS1890 100 AS1890 AS2004 AS288 as-in: AS1888 100 AS1888 as-in: AS2122 200 AS2122 AS2600 as-in: AS2600 100 AS2600 as-in: AS3333 100 AS3333 as-out: AS1103 AS1104 as-out: AS1890 AS1104 as-out: AS1888 AS1104 as-out: AS2122 AS1104 as-out: AS2600 AS1104 as-out: AS3333 AS1104 default: AS1103 100 guardian: ripe-op(a)nikhef.nl admin-c: Rob Blokzijl tech-c: Marten Terpstra remarks: peers with AS2122 and AS2600 are RR test peers notify: tony(a)ripe.net notify: marten(a)ripe.net changed: tony(a)ripe.net 940426 source: RIPE As of B1 the same query will produce: ripe-1nn.txt August, 1994 - 14 - aut-num: AS1104 descr: NIKHEF-H descr: Science Park Watergraafsmeer descr: Amsterdam, The Netherlands as-in: from AS1103 100 accept AS1103 as-in: from AS1890 100 accept AS1890 AS2004 AS288 as-in: from AS1888 100 accept AS1888 as-in: from AS2122 200 accept AS2122 AS2600 as-in: from AS2600 100 accept AS2600 as-in: from AS3333 100 accept AS3333 as-out: to AS1103 announce AS1104 as-out: to AS1890 announce AS1104 as-out: to AS1888 announce AS1104 as-out: to AS2122 announce AS1104 as-out: to AS2600 announce AS1104 as-out: to AS3333 announce AS1104 default: AS1103 100 guardian: ripe-op(a)nikhef.nl admin-c: Rob Blokzijl tech-c: Marten Terpstra remarks: peers with AS2122 and AS2600 are RR test peers notify: tony(a)ripe.net notify: marten(a)ripe.net changed: tony(a)ripe.net 940426 source: RIPE This is an important subtle change and anyone using tools should be aware of this change. To provide some backward compatibility it is possible to use the "-S" flag to the whois server to produce output without the added syntax information. A whois client supporting this flag will also be made available at B1. ripe-1nn.txt August, 1994 - 15 - 5. Visible Changes and Actions Required by User Group The effects of the B1/B2 changes and the actions needed by the dif- ferent groups of RIPE database users are summarised below. This is intended as a check list for members of those user groups. It should be noted most readers of this document will belong to more than one group. 5.1. Routing Registry Guardians This group comprises those who maintain the information in the Rout- ing Registry part of the database: "aut-num" and "community" guardians and guardian file maintainers. This group will see the most changes and need to take some actions. 5.1.1. Between now and B1 Action Change entries in guardian files to exactly match single database objects. 5.1.2. After B1 and before B2 Action Check and update the "mntner" objects generated in the guardian accounts, thus establishing a mapping between guardian files and "mntner" objects. Action Check the file of generated "route" objects and modified "inet- num" objects in the guardian account for errors and report those to the NCC. 5.1.3. After B2 Change Guardian file mechanism is no longer needed and disabled. Change Route objects created. Action Clean up guardian accounts. Action Align any locally stored objects with the split objects. Action Check "route" objects for remarks containing "ias-int" attributes and create "inet-rtr" objects where necessary. ripe-1nn.txt August, 1994 - 16 - 5.2. Local Registries This is the group who maintains "inetnum" objects. They will see the consequences of the "inetnum"/"route" split and will be able to use the new authorisation scheme. 5.2.1. Between now and B1 No changes or actions before B1. 5.2.2. After B1 and before B2 Change Now possible to store multiple "inetnum" objects covering the same address space at different levels. Change All representations decribed in [1] can be used for object sub- mission. Change New authorisation now available. Action Coordinate authorisation on objects maintained by more than one party. Action Prepare for "inetnum"/"route" split especially when storing data locally. Action Check "inetnum" objects for "ias-int" attributes and create "inet-rtr" objects where necessary. 5.2.3. After B2 Change Some attributes obsoleted and some moved to "route" object. Action Align any locally stored objects with the split objects. Action Stop submitting obsolete/moved attributes. 5.3. Maintainers of other Objects This group will basically only see added authorisation features and the need for coordination of this when multiple parties maintain an object. ripe-1nn.txt August, 1994 - 17 - 5.3.1. Between now and B1 No changes or actions before B1. 5.3.2. Change New authorisation now available. Action Coordinate authorisation on objects maintained by more than one party. 5.3.3. After B2 No changes or actions after B2. 5.4. Users of RIPE DB Information This is the group who queries the RIPE whois server and/or uses the database files. 5.4.1. Between now and B1 Action Check and adapt tools for the effects of B1: queries will return less specific matches if no exact match can be found. 5.4.2. After B1 and before B2 Change Network number queries can be classless and return less spe- cific matches if no exact match is found. Change Ability to obtain less and more specific matches on network number queries. Action Check and prepare tools for the effects of B2: "route"/"inetnum" split, obsoleted attributes, new attributes, syntactic sugar returned by default in "aut-num". 5.4.3. After B2 Change Effects of "route"/"inetnum" split will be visible. 6. Results The results from this three phase transition will the following ripe-1nn.txt August, 1994 - 18 - achievements. 1) A fully supported classless database (as of B1). 2) A new and improved authorisation and maintenance mechanism (as of B2). 3) Full support of ripe-81++ features (completed by B2 and most available from B1). As with any transition of this type some change of data is unavoid- able and a number of "big bang" days need to be factored in. How- ever, the end result is a clear improvement to both the RIPE alloca- tion and routing registry. Throughout the whole transition period the RIPE NCC will be available to make emergency changes to data if needed and deemed to be critical. All queries should be directed towards ncc(a)ripe.net. 7.

The Top 20 and some deltas
by Tony Bates 31 Aug '94

31 Aug '94

This is an auto-generated mail on Wed Aug 31 21:10:00 MET DST 1994 As stated above this is auto-generated so it is not checked before it leaves my workstation. This is a list of the "Top 20" players who if CIDRizing at the AS level could make a significant gain in the size of Internet routing tables. This may be an over-estimation but it is hoped that this can act as an incentive for the "Top 20" and others to look at their CIDR capability. This report is available as: ftp://ftp.ripe.net/cidr/stats/Top-20.31Aug94 The current (and of course this one today) report is always accessible as: ftp://ftp.ripe.net/cidr/stats/Top-20 A full summary of all the ASes seen in the Internet can be seen by looking in: ftp://ftp.ripe.net/cidr/stats/AS* Please also find a summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does some indication of ASes participating in CIDR. More information can be found in: ftp://ftp.ripe.net/cidr/stats/Delta.* Also, for a short time this gives details of any possibly interesting aggregates currently seen in the routing. Interesting here means not a aggregate made as a chuck of classful routes. This a daily snaphost of changes in classfull routes being withdrawn and added. the deltas are calculated over a rolling 7 day period. Please bear in mind this is purely a "snapshot" and a large flucuation could be caused by a connectivity problem for example. However, this does give some indication of service providers that are moving to classless routing.

A summary of changes of RIPE-81++ from last RIPE meeting
by Tony Bates 26 Aug '94

26 Aug '94

This is the promised summary of changes of document to help focus discussion at the forthcoming RIPE meeting. URL: ftp://ftp.ripe.net/ripe/drafts/ripe-81++.changes.txt -- Text version URL: ftp://ftp.ripe.net/ripe/drafts/ripe-81++.changes.ps -- PS version --Tony. Summary of changes in RIPE-81++ from previous RIPE Meeting. Tony Bates 23rd August, 1994 1. Introduction In an effort to focus discussion for the forthcoming RIPE meeting in Lisbon in September I have made a brief outline of the changes to the RIPE-81++ draft from the last RIPE meeting. It is divided into two sections; basic and major changes. The major changes section will be most relevant for the forthcoming RIPE meeting and in par- ticular the RIPE routing working group. The latest RIPE-81++ draft is available from: URL: ftp://ftp.ripe.net/ripe/drafts/ripe-81++.{ps,txt} 2. Basic Agreed Changes This sections details the changes that were agreed and have been fully incorporated into the current draft of RIPE-81++. All the changes are with respect to the RIPE-81++ proposal tabled at the RIPE meeting in Amsterdam in May, 1994. In each case only very brief detail is given as these changes have been agreed by consensus. Network Lists. Add the use of network lists in the routing policy expression com- ponent. This will be in the form proposed by Merit. i.e. list of nets separate by commas within braces: { 35.0.0.0/8, 192.87.45.0/24 } Extension to "default" attribute There is a set of additional OPTIONAL components added to the default attribute. See RIPE-81++ for more details. - 2 - Syntactic SUGAR We added in the additional reserved words to make the syntax clearer. NOTE: the reserved words will all be in lower-case to dis- tinguish them from special policy keywords and communities. Here is a summary of current SUGAR to add and where. accept announce exclude from to transit Examples of the usage of the reserved words are: as-in: from neighborAS accept route as-out: to neighborAS announce route as-exclude: exclude ASpath to destination as-transit: transit ASpath to destination default: from neighborAS accept route default: to neighborAS announce route Note: that as-transit is an experimental attribute. See below. Network Representation We used the "prefix length" notation documented in the classless proposal paper. i.e. 35.0.0.0/8 192.87.45.0/24 "as-reject" changed to "as-exclude" The text remained the same. The name of the attribute changed. 3. Major Changes This section details the major changes with respect to the draft - 3 - presented at the RIPE meeting in Amsterdam in May, 1994. The "component" attribute is gone The component attribute was dropped as it was deemed to be too com- plex to understand and too difficult to maintain and guard. The out- come of this is two new attributes and one new object that facili- tate the functionality of the component attribute 1) withdrawn attribute Often is is useful to show a route that has been withdrawn from the routing table. The has become very important now that CIDR is deployed as service providers start to withdraw more specific routes from an aggregate. 2) hole attribute For tools in can be very useful to indicate "holes" in a CIDR aggregate where there is currently no expected connectivity. 3) inet-rtr object This allows you to detail the interfaces of a router as well as the AS the router belong to. This is extremely useful for routes/networks which fall into the category of what used to be called "inter-as networks" described by the proposed to be obsoleted "ias-int" attribute in the "inetnum" object. This object is described in: Bates, T., "Specifying an `Internet Router' in the Routing Registry", July, 1994. DRAFT. URL: ftp://ftp.ripe.net/drafts/inet-rtr.{ps,txt} The "interas-in" and "interas-out" attributes. This is an additional set of attributes added to detail local poli- cies between any two ASes which have more than one interconnecting link. This description is necessary only if the ASs are connected in more than one way and the routing policy and differs at these two connections. Example: LINK1 193.0.1.1 +----------+ 193.0.1.2 | | AS1------AS2== ==AS3-----AS4 | | 193.0.1.5 +----------+ 193.0.1.6 LINK2 - 4 - Descriptions of interas policies do not replace the global pol- icy described in as-in, as-out and other policy attributes which always describes the global policy between the two ASes. The interas-in/out attributes only specify local variations to the glo- bal policy described in the other attributes. If the global policy mentions more routes than the local policy then local preferences for these routes are assumed to be equal for all links. A simple extendable syntax has been defined for this additional information. For details of this refer to the ripe-81++ draft. Possible outstanding issues with interas-in/interas-out A major discussion point came from these attributes The ordering There were two styles of ordering proposed. A) interas-in: <my id> [from] ASxx <neighbor id> <pref> <pol- icy> B) interas-in: [from] ASxxx <my id> <neighbor id> <pref> <pol- icy> Fortunately, an executive decision has been made by the chair of the RIPE routing group to go with option B. The main reason behind this is for consistency with the as-in and as-out attri- butes. Clarification of evaluation of operators. Some text has been added to clarify the ordering of how the logical operators are evaluated in routing policy expressions and what they actually mean. It was recognised that ripe-81++ was weak on this point. This text is taken verbatim from the ripe-81++ draft: .... <routing policy expression> can take the following formats. 1. A list of one or more ASes, AS Macros, Communities or Net- work Lists. A Network List is a list of network numbers in prefix length format, separated by commas, and surrounded by curly brackets (braces, i.e. `{' and '}'). Examples: - 5 - as-in: from AS1103 100 accept AS1103 as-in: from AS786 105 accept AS1103 as-in: from AS786 10 accept AS786 HEPNET as-in: from AS1755 110 accept AS1103 AS786 as-in: from AS3333 100 accept {192.87.45.0/16, 128.141.0.0/16} 2. A set of KEYWORDS. The following KEYWORD is currently defined: ANY this means anything the neighbour AS knows. 3. A logical expression of either 1 or 2 above The current logical operators are defined as: AND OR NOT This operators are defined as true BOOLEAN operators even if the operands themselves do not appear to be BOOLEAN. Their operations are defined as follows: Operator Operation Example OR UNION AS1 OR AS2 | +-> all routes in AS1 or AS2. AND INTERSECTION AS1 AND HEPNET | +-> a route in AS1 and belonging to community HEPNET. NOT COMPLEMENT NOT AS3 | +-> any route except AS3 routes. Rules are grouped together using parenthesis i.e "(" and ")". The ordering of evaluation of operators and there associa- tion is as follows: Operator Associativity () left to right NOT right to left AND left to right OR left to right - 6 - NOTE: if no logical operator is given between ASes, AS- macros, Communities, Network Lists and KEYWORDS it is implicitly evaluated as an `OR' operation. The OR can be left out for conciseness. However, please note the opera- tors are still evaluated as below so make sure you include parentheses whenever needed. To highlight this here is a simple example. If we denoted a policy of for example; from AS1755 I accept all routes except routes from AS1, A2 and AS3 and you enter the following as-in line. as-in: from AS1755 100 accept NOT AS1 AS2 AS3 This will be evaluated as: as-in: from AS1755 100 accept NOT AS1 OR AS2 OR AS3 Which in turn would be evaluated like this: (NOT AS1) OR AS2 OR AS3 -> ((ANY except AS1) union AS2) union AS3) --> (ANY except AS1) This is clearly incorrect and not the desired result. The correct syntax should be: as-in: from AS1755 100 accept NOT (AS1 AS2 AS3) Producing the following evaluation: NOT (AS1 OR AS2 OR AS3) -> (ANY) except (union of AS1, AS2, AS3) Which depicts the desired routing policy. Note that can also be written as below which is perhaps somewhat clearer: as-in: from AS1755 100 accept ANY AND NOT (AS1 OR AS2 OR AS3)

The Top 20 and some deltas
by Tony Bates 24 Aug '94

24 Aug '94

This is an auto-generated mail on Wed Aug 24 21:10:00 MET DST 1994 As stated above this is auto-generated so it is not checked before it leaves my workstation. This is a list of the "Top 20" players who if CIDRizing at the AS level could make a significant gain in the size of Internet routing tables. This may be an over-estimation but it is hoped that this can act as an incentive for the "Top 20" and others to look at their CIDR capability. This report is available as: ftp://ftp.ripe.net/cidr/stats/Top-20.24Aug94 The current (and of course this one today) report is always accessible as: ftp://ftp.ripe.net/cidr/stats/Top-20 A full summary of all the ASes seen in the Internet can be seen by looking in: ftp://ftp.ripe.net/cidr/stats/AS* Please also find a summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does some indication of ASes participating in CIDR. More information can be found in: ftp://ftp.ripe.net/cidr/stats/Delta.* Also, for a short time this gives details of any possibly interesting aggregates currently seen in the routing. Interesting here means not a aggregate made as a chuck of classful routes. This a daily snaphost of changes in classfull routes being withdrawn and added. the deltas are calculated over a rolling 7 day period. Please bear in mind this is purely a "snapshot" and a large flucuation could be caused by a connectivity problem for example. However, this does give some indication of service providers that are moving to classless routing.
