The Cidr Report
by Tony Bates 09 Jun '01

09 Jun '01

This is an auto-generated mail on Fri Jun 8 23:00:00 PDT 2001 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. 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is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes.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 xara.net for giving me access to their routing tables once a day. Please send any comments about this report directly to me.

The Cidr Report
by Tony Bates 02 Jun '01

02 Jun '01

This is an auto-generated mail on Fri Jun 1 23:00:00 PDT 2001 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. 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is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes.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 xara.net for giving me access to their routing tables once a day. Please send any comments about this report directly to me.

Changes to ARIN inaddr.arpa zone generation process

28 May '01

[Apologies for duplicate messages] CHANGES TO ARIN IN-ADDR.ARPA ZONE GENERATION PROCESS Please not the information in the message below from Ginny Listman, Director of Engineering at ARIN, the American Registry for Internet Numbers. The message relates to changes in the generation of the in-addr.arpa zone files by ARIN. This information is specifically pertinent to organisations with networks currently reverse-delegated by ARIN. Please note that this does not directly affect organisations with networks reverse-delegated by the RIPE NCC. Kind regards, RIPE NCC +------------------------------------------------+ | RIPE NCC (Network Co-ordination Centre) | | <ncc(a)ripe.net> | | | | http://www.ripe.net | | Singel 258, 1016 AB Amsterdam, The Netherlands | | Tel: +31-20-5354444 | | Fax: +31-20-5354445 | +------------------------------------------------+ -----Begin Forwarded Message ----- From: On Behalf Of ARIN IN-ADDR Role <inaddr(a)arin.net> Sent: Thursday, May 17, 2001 4:18 PM To: arin-announce(a)arin.net Cc: nanog(a)nanog.org Subject: in-addr.arpa zone generation process to change When ARIN began operations, one of the tasks that it took over from the InterNIC was the generation of the zone file for the in-addr.arpa domain. In order to correct long-standing issues with the data in the zone file, new software is being deployed. ARIN policy states that allocation subscribers with networks of /16 or shorter prefix are responsible for maintaining all in-addr.arpa domain records for reassignments within the block. They must also provide to ARIN the host names of the nameservers hosting any delegations. ARIN will continue to host domain records for delegations of networks with prefixes longer than /16. The in-addr.arpa zone will contain delegations for any /8 containing nameservers within ARIN's database. For address space not covered via these delegations, the in-addr.arpa domain will contain delegations for /16's with nameservers. For address space still not delegated and as mentioned above, the in-addr.arpa domain will contain delegations of /24's for networks longer than a /16 containing in-addr nameservers. In all cases, the most specific reassignment with nameservers at each octet boundary will prevail. ARIN is making every effort to ensure that any impact from these changes will not disrupt in-addr.arpa name services. If you have concerns whether in-addr.arpa name services will be impacted for your networks, please review examples of the changes to occur at: http://www.arin.net/inaddr/inaddr-examples.txt If you still have concerns after reviewing these examples, please direct specific questions about your networks to inaddr(a)arin.net. We have tentatively scheduled implementation of the new process for late May or early June. A specific date will be announced several days prior to the cut-over on both the arin-announce and nanog mailing lists.

The Cidr Report
by Tony Bates 26 May '01

26 May '01

This is an auto-generated mail on Fri May 25 23:00:00 PDT 2001 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. 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 xara.net for giving me access to their routing tables once a day. Please send any comments about this report directly to me.
