The Cidr Report

This is an auto-generated mail on Fri Jun 29 23:00:01 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is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes.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 GX Networks for giving me access to their routing tables once a day. Please send any comments about this report directly to me.

This is an automated weekly mailing describing the state of the Internet Routing Table as seen from APNIC's router in Japan. Daily listings are sent to bgp-stats(a)lists.apnic.net For a graphical representation, please see http://www.apnic.net/stats/bgp. If you have any comments please contact Philip Smith <pfs(a)cisco.com>.

Unprocessed update mails to RIPE Whois Database
by RIPE Database Administration 25 Jun '01

25 Jun '01

Dear Colleagues, [apologies for duplicate messages] Between Thu Jun 14 16:19:15 2001 CEST and Fri Jun 15 10:34:29 2001 CEST, due to a failure in our systems which processes updates to RIPE Whois Database, the update message have not been processed, instead they were only stored. Most of the users who sent those messages noticed that they didn't get any acknowledgement from our system, and re-sent their updates. Realizing the failure on Friday Jun 22, we tried to find out those messages which were _not_ re-sent by the user, and we processed them. Thus, please don't be confused if you've got a late acknowledgement message. If you have any questions about the incident, please contact <ripe-dbm(a)ripe.net>. We are sorry about the inconvenience this caused. Best Regards, Engin Gunduz RIPE NCC Database Group

The Cidr Report
by Tony Bates 16 Jun '01

16 Jun '01

This is an auto-generated mail on Fri Jun 15 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 GX Networks for giving me access to their routing tables once a day. Please send any comments about this report directly to me.
