It is not checked before it leaves my workstation. However, hopefully
you will find this report interesting and will take the time to look
through this to see if you can improve the amount of aggregation you
perform.
Check http://www.employees.org/~tbates/cidr-report.html for a daily
update of this report.
NEW: Check http://www.employees.org/~tbates/cidr-report-region.html for
the regional version of this report.
NEW: Check http://www.employees.org/~tbates/autnums.html for a complete
list of autonomous system number to name mappings as used by the CIDR-Report.
The report is split into sections:
0) General Status
List the route table history for the last week, list any possibly
bogus routes seen and give some status on ASes.
1) Gains by aggregating at the origin AS level
This lists the "Top 30" players who if they decided to aggregate
their announced classful prefixes at the origin AS level could
make a significant difference in the reduction of the current
size of the Internet routing table. This calculation does not
take into account the inclusion of holes when forming an aggregate
so it is possible even larger reduction should be possible.
2) Weekly Delta
A summary of the last weeks changes in terms of withdrawn and
added routes. Please note that this is only a snapshot but does
give some indication of ASes participating in CIDR. Clearly,
it is generally a good thing to see a large amont of withdrawls.
3) Interesting aggregates
Interesting here means not an aggregate made as a set of
classful routes.
Thanks to GX Networks for giving me access to their routing tables once a
day.
Please send any comments about this report directly to CIDR Report <cidr-report(a)cisco.com>.

Dear colleagues,
the Routing-WG minutes of our sessions at RIPE-41 had already been published
on the web in February
(http://www.ripe.net/ripe/wg/routing/r41-minutes.html) For those who have
not yet seen them, I redistribute them with some very slight editorial
changes and one URL correction.
Thanks again to Matthew Williams-Bywater for compiling this!

Chair: Joachim Schmitz - JS395-RIPE
Scribes: Matthew Williams-Bywater
Participants: 150 (1st session) / 78 (2nd session)
A. Preliminaries
Joachim welcomed us all to the meeting and declared it open. The
participants' list was then handed out by the chair and Matthew Williams
from RIPE-NCC volunteered to take the minutes.
The proposed agenda for this session and minutes from the previous meeting
at RIPE40 were approved without hesitation by the attendees.
Action points from earlier meetings:
37.R2 on RIS team, Henk Uijterwaal
Implement route flap analysis from RIS data
-ongoing-
39.R1 on J.Schmitz, D.Kessens and F.Parent
Initiate IPv6 IRR task force
-done-
The item above was considered done by participants. Florent
Parent has already published an Internet draft proposal,
"RPSL extensions for IPv6 and Multicast Routing Policies",
which can be found at URL:
http://www.normos.org/ietf/draft/draft-parent-multiprotocol-rpsl-00.txt
and work in the task force is running now.
40.R1 on Kurt Keyser, Joachim Schmitz and Philip Smith
Create "Multihoming Document" for LIRs
-ongoing-
First Session: 15-January-2002
------------------------------
B. Henk Uijterwaal: Routing Information Service, Status and Plans
Presentation available at URL:
http://www.ripe.net/ripencc/pub-services/np/Talks/0201_RIPE41/
Two Route Collectors will be added to the Routing Information Service:
one located at Netnod-IX in Stockholm and another at NSPIXP2 in Tokyo.
The latter has received a feed from APNIC since August last year, but
its announcement as a service was delayed until January 2002 due to
hardware issues. Next steps include finding one or two locations in
the United States and investigating the added value of more collectors
in Europe.
Currently, Route Collectors are present at:
* RIPE-NCC
* LINX, London
* SFINX, Paris
* AMS-IX, Amsterdam
* CIXP, Geneva
* VIX, Vienna
* NSPIXP2, Otemachi (Tokyo)
[Planned: Netnod-IX, Stockholm]
Total of 178 BGP sessions
As part of the continuous improvement of the RIS, a 700GB RAID was
installed at the RIPE NCC. It is estimated that the new hardware will
fulfil storage needs until the end of this year. Additional changes and
improvements will be announced to the mailing list, ris-users(a)ripe.net,
maintained by majordomo at RIPE NCC. Hopefully, the mailing-list will
also become the natural forum for discussions about RIS data.
Since the last meeting, manuals and FAQ's have been added to the web site.
The manual pages contain typical examples on usage and interpretation of
different RIS query options. More cases will be appended in the future.
Due to the time-gap of one hour between data collection and insertion, it
was
decided to implement a Looking Glass on each of the Remote Route
Collectors.
It has most of the standard options found elsewhere on the Internet. A new
query type has been created for users as an attempt to target flaps, the
RIS TopN Utility. It produces lists of prefixes on demand, where high
withdrawal or announcement activity was registered over a specified time
interval. High counts could indicate some kind of problem for certain
routes.
The RIS team will start running the queries regularly to produce monthly
TopTen reports over "active" prefixes and AS numbers.
The utility can be found at URL:
http://abcoude.ripe.net/ris/topten.cgi
Furthermore, Henk and his team will continue its work on finding "route
flaps". In February 2002, a student will start devoting his time to an
experiment that involves announcing/withdrawing fake routes and observing
when changes are registered by Remote Route Collectors. A collaboration
of people from AT&T Research and RIPE NCC will analyze results from the
experiments.
Another project, the RISreport, has had to be redesigned due to scalabity
issues when adding new plots. The switch to the re-implementation will
commence within the next few weeks.
There were no questions on this presentation.
C. Engin Gunduz: Routing Registry Consistency Check Project
Slides available at URL:
http://www.ripe.net/ripe/meetings/archive/ripe-41/presentations/database-rr…
Engin held a short introductory presentation regarding the RRCC project and
its future. The main objectives of the project are targeting
inconsistencies
between the RIPE Routing Registry, making the RIPE RR reflect de facto
Internet Routing Policies and, by making it more accurate, also more useful
to Network Administrators. The RRCC will use RIS data, currently from
RRC00,
and compare it to information stored in the RIPE RR.
RIPE201, published in December 2001, provides an overview of the project
and
is intended to solicit input from interested parties. It can be found at
URL:
http://www.ripe.net/ripe/docs/rr-consistencycheck.html.
There is also a prototype available on the RRCC web site.
See URL: http://www.ripe.net/rrcc/
The prototype is updated daily using, as previously mentioned, RIS data and
provides the following query types:
* unregistered, but advertised prefixes
* registered, but not advertised prefixes
* unregistered peerings
Future plans include making different subscription services available to
the
community and producing metrics that measure improvements in RR data
quality. Community feedback can be sent to RRCC(a)ripe.net.
There were also no questions on this presentation.
D. Philip Smith: Internet Routing Table Analysis Update
Slides available at URL:
http://www.ripe.net/ripe/meetings/archive/ripe-41/presentations/routing-rt-…
lysis/
Philip Smith has added a number of new variables to the Internet Routing
Table statistics, which are available at URL:
http://www.apnic.net/stats/bgp/
New variables include:
* "Count Unique Prefixes" - Eliminate all subnets of prefixes appearing in
the routing table, e.g. 158.43.0.0/16 is announced, but all subnets are
dropped/ignored. Represents the Internet Routing Table's smallest
theoretical size without loosing address space, but may lead to routing
problem if used.
* "Prefixes after Maximum Aggregation" - Eliminate all subnets of prefixes.
appearing in the Internet Routing Table that appear originating from the
same AS, e.g. 158.43.0.0/16 is announced from AS1849 and all subnets from
the same AS are dropped/ignored. Represents the aggregation effort from
AS,
not taking traffic engineering into account, and the smallest theoretical
size of the routing table without losing any detailed reachability
information.
* "IP Addresses in Use" - Previous error which over-counted address space
fixed.
* "Origin-only ASes" - Counts ASes which only originate prefixes and are
not
seen in transit paths from Smith's BGP view.
* "Transit-only ASes" - Counts ASes which are NOT originating prefixes and
only in transit paths from BGP view.
The Internet Routing Table had 107232 entries on the 11th of January from
Smith's view. On the same day, counts for 'Unique Prefixes' and 'Prefixes
after Maximum Aggregation' were 52095 and 71370 respectively, where the
latter gives us a theoretical estimate of the routing table's size if
optimal
aggregation were to be employed. Philip had also observed some interesting
trend changes in the BGP table since early last year after the "Dot-Com"
collapse. A previously non-linear growth of the amount of tables entries
has
practically stabilized itself at approximately 107k routes. Similar trends
can also be seen in the amount of announced ASes on the Internet. Several
other examples on how to interpret statistics, including comparative
observations between RIR regions, were presented at the meeting.
There were no additional questions to that presentation.
E. Andre Oppermann: BGPDNS - "Using BGP Topology Information for DNS RR
Sorting a Scalable Way of Multi-Homing"
Presentation available at URL:
http://www.ripe.net/ripe/meetings/archive/ripe-41/presentations/routing-opp…
an/
BGPDNS is both concept and protocol for achieving server multi-homing
without
needing your own AS and PI address space. Reasons for multi-homing vital
servers to several ISPs include:
* Link Redundancy
* Load-Balancing
* Independency
However, this approach has drawbacks for the community as large:
* Fragmentation of IP address space
* Excessive memory and CPU requirements on Internet Core Routers
* Exhaustion of current AS number space
Considering that BGPDNS overcomes many disadvantages of traditional
multi-homing, it may someday become the viable alternative. The method does
not require an unique AS number or PI address space, while still fully
maintaining aggregates. When a request is received by the authorative DNS
at the site, it will interact with the BGPDNS server, via the protocol with
the same name, to determine which of its 'A Records', all corresponding to
a particular server, is the best reachable IP for the requester. This can
be achieved by having the BGPDNS server establish its own listening-only
BGP sessions with route servers at each upstream provider.
The mechanisms for determining which IP that should be listed first in the
DNS response, i.e. used by the source, are relatively easy to understand.
Firstly, the BGPDNS server performs a "show ip bgp" for the requesters IP
to establish the best path back to the source and, secondly, another "show
ip bgp regexp" for the left-most AS in order to determine the aggregate
originating from there. The A record IP that belongs to that address space
will be given priority over the others. When the DNS server sees the
priority, it will list the corresponding IP first in the response packet
sent back to the requester. The source will then use this destination IP
to establish a session with the target server. More detailed information
can be attained by reading the RFC draft.

Second Joint Session with the Database WG: 16-January-2002

F. Marc Blanchet: IPv6 and Multicast routing policies using RPSL
Slides can be found at URL:
http://www.viagenie.qc.ca/en/ipv6/presentations/ripe41-rpsl.pdf
# Editorial note: Compared to the discussion this summary comes delayed.
# In the meantime, there was some more discussion on the mailing list,
# a new proposal from the RIPE NCC, and a meeting of interested people
# during the IETF and a new draft by the RIPE NCC to be presented at
# RIPE42. Nonetheless, the summary is provided again for completeness.
Currently, RPSL doesn't define IPv6 nor multicast routing policies.
At RIPE-40, a task force was initiated to document the usage of
above in current classes and then, if required, define modifications
to the present implementation of RPSL.
The current proposal aims at making the changes generic, i.e not only
limited to IPv6 and multicasting, and also minimizing the number of
additional classes/attributes. These goals are based on ideas from
Florent Parent's initial draft and discussions on the mailing list
(rpslng(a)ripe.net) and at IETF52.
See URL for the latest draft proposal during RIPE41:
http://www.normos.org/ietf/draft/draft-parent-multiprotocol-rpsl-00.txt
Although the current RPSL database will remain intact, the suggestions
imply
that a new server will be required for both the present database and multi-
protocol extensions. Obviously, clients and current tools, e.g. IRRtoolset,
will also have to support these changes.
Next steps include porting the IRRtoolset to support the new extensions,
moving the document forward at IETF and continuing the discussion on the
mailing list. Members can subscribe to it by sending an email to:
rpslng-request(a)ripe.net.
Discussion - "The Inconsistent Syntax of Proposed Sub-Attributes Afi/Safi":
João Luis Silva Damas (RIPE NCC) - a) Does not like afi/safi because its
not easily read/written by humans, easily processed by machines though.
Better to do classes. b) Prune things that are not used or required.
c) Describe transition IPv4 -> IPv6, in particular tunnels.
David Kessens (Nokia) - a) Wants to add minimal IPv6 support b) Does not
want to prune nor simplify RPSL, maybe just exclude unused things c) No new
classes, just add/modify attributes to get running more swiftly. However,
requires many changes to all tools, not only IRRToolSet, but also privately
developed tools.
Ping Lu (Cable & Wireless) - Supports new classes as well.
Andrei Robachevski (RIPE NCC) - a) Also supports new classes. Does not want
to complicate RPSL just to make it appear more intelligent. b) Charter so
far concerns only extensions of RPSL. We also need RPS auth.
David - Distinguish between new classes, new attributes and new sub-
attributes.
Ping - From an operational standpoint: If we want to configure an IPv4
route,
so we are looking for an IPv4 route class. Same goes for IPv6. If the
database offers two distinct classes, then the user will only need to use
one hash for deriving route.
Larry Blunk (Merit Network) - New commands would have to be added to the
server. Same would be required for IRRToolSet, IRRd, whois etc.
David - a) The difference between IPv4 and IPv6 can easily be found by
parser, but does this include future address formats? Probably not, so
please
don't use implicit information. b) Another idea would be to identify topics
by commencing work on a deployment plan.
Per Heldal (Private) - What about using a proxy as front-end to the
database
as a method for cloaking syntax or attribute changes from tools and user?
Wilfried Woeber (UniVie/ACOnet) - Are the IPv4 and IPv6 players the same?
Is the infrastructures the same? Do we have an issue at all?
Ping - Again: Please don't change the sub-attribute context. Much too
complicated and will require changes to existing modules that analyze or
parse the present RPSL.
Gert Doering (SpaceNet) - Same AS numbers are used, meaning that IPv4 and
IPv6 attributes must be in the same class.
Ping - Agrees, but more concerned about sub-attribute context
Joachim Schmitz (AOL) summarizes the discussion:
* We need to continue our debate regarding the charter: RPSL
(IPv6, multicast, transitional elements) and RPS Auth.
* There is currently no consensus on the future apparition of
RPSLng. We will have ask different groups to take on certain
tasks and then develop proposals.

Hi,
I just ran a little study regarding unresolvable IPs that request web
services from us against the statistics file APNIC, ARIN, and RIPE issue. I
am posting this in the hope that the RIRs would correct the errors or
missing data.
Those statistics files are supposed to contain all the IPv4 space assigned;
they can be found at:
1.1- apnic:
ftp://ftp.apnic.net/pub/stats/apnic/
1.2- ripe:
ftp://ftp.ripe.net/ripe/stats/
1.3- arin:
ftp://ftp.arin.net/pub/stats/arin/
The raw result is here:
http://www.serveurDEDIE.com/stats/no-stat.txt
The format is: <status> <IP> [<whois server> <owner from the whois>
[ILLEGAL]]
We have found several things:
* there are some IPs that should be in the statistics file but are missing.
Some IPs have got an associated whois record, but are not in the statistics.
I would be nice if the RIRs could fix that. Please see by yourself:
$ grep whois\.apnic\.net no-stat.txt
$ grep whois\.arin\.net no-stat.txt
$ grep whois\.ripe\.net no-stat.txt
* there are some few IPs that are totally unknown from the registries:
$ grep no-whois no-stat.txt
No-stat-no-whois: 196.2.95.17
No-stat-no-whois: 211.234.140.220
$ grep IANA no-stat.txt
No-stat: 90.0.0.4 [whois.arin.net] IANA
* there are some inconsistent pointers in whois between ARIN and RIPE.
Example with 159.157.251.43:
"
$ whois -a 159.157.251.43
[whois.arin.net]
European Regional Internet Registry/RIPE NCC (NET-RIPE-159) RIPE-159
159.156.0.0 -
159.157.255.255
Schegel Corporation (NET-BTR-SSG-NET) BTR-SSG-NET159.157.0.0 -
159.157.255.255
"
Here ARIN says that the bloc has been further assigned to RIPE:
"
These addresses have been further assigned
to European users. Contact information can
be found in the RIPE database at whois.ripe.net
"
But if you follow that pointer:
$ whois -r 159.157.251.43
[whois.ripe.net]
% This is the RIPE Whois server.
% The objects are in RPSL format.
% Please visit http://www.ripe.net/rpsl for more information.
% Rights restricted by copyright.
% See http://www.ripe.net/ripencc/pub-services/db/copyright.html
inetnum: 0.0.0.0 - 255.255.255.255
netname: IANA-BLK
descr: The whole IPv4 address space
country: NL
admin-c: IANA1-RIPE
tech-c: IANA1-RIPE
status: ALLOCATED UNSPECIFIED
remarks: The country is really worldwide.
remarks: This address space is assigned at various other places in
remarks: the world and might therefore not be in the RIPE database.
mnt-by: RIPE-NCC-HM-MNT
mnt-lower: RIPE-NCC-HM-MNT
mnt-routes: RIPE-NCC-NONE-MNT
changed: bitbucket(a)ripe.net 20010529
source: RIPE
"
You see that RIPE has in fact no record for this IP. There are quite a few
such problems, and they are no easy to spot.
* Lastly, but that is already well known, some IPs, mainly in the RIPE
space, are only ALLOCATED (not ASSIGNED) but still in use. The study will
look for that when it has to lookup an IP the RIPE database and will mark
the result (bare with the bug please) qith "<font color=red>ILLEGAL</font>".
You can find those records with:
$ grep \>ILLEGAL\< no-stat.txt
I would really appreciate if the RIRs could fix the records that are missing
in the statistics file, i.e. those that have a whois record but are not in
the statistics.
Thank you in advance
