This is an auto-generated mail on Fri Apr 13 23:00:02 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is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes.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.

by John Crain 09 Apr '01

09 Apr '01

FYI: This is just a quick heads up, my apologies if you recieve duplicate copies. IANA has recently allocated the following address ranges to the RIPE NCC Regional Internet Registry. 80.0.0.0 - 81.255.255.255 These will start to be allocated to ISPs shortly. You may wish to adjust any filters you have in place accordingly. John Crain ICANN

RIPE Database Software Version 3.0.
by DB-News 05 Apr '01

05 Apr '01

Dear Colleagues, [Apologies for multiple messages]. The RIPE NCC is pleased to announce the release of Version 3.0 of the RIPE Database software. This software is compliant with both RPSL (RFC-2622) and RPS-Security (RFC-2725). You can download this release by anonymous ftp from the following URL: ftp://ftp.ripe.net/ripe/dbase/reimp/ripe-dbase-3.0.tar.gz We remind you that you can also test the functionality of this release of the new RIPE Whois server in 2 ways: - by querying the host rpsl.ripe.net at port 43; you will find there a Near-Real-Time Mirror of the RIPE Database; this mirror is in RPSL format; - by using the RIP Test Database; you can send test updates to this database at the address <auto-rip(a)ripe.net>, and you can query this database at reimp.ripe.net port 4343. We would be very pleased if you could test this release in both ways, and send us your comments. Comments and bug reports may be sent to the <db-beta(a)ripe.net> mailing list. To subscribe to this list, send a message to <majordomo(a)ripe.net> with the line: subscribe db-beta in the body of your message. This is a moderated mailing list so some delays in subscription are possible. Version 3 of the RIPE Database software will be deployed on the RIPE Whois server on 23 April 2001. Please see http://www.ripe.net/rpsl/ for more information on how this will affect you. There is a mailing list to discuss the migration to the new service, <reimp-mig-tf(a)ripe.net>. To subscribe, send a message to <majordomo(a)ripe.net> with the line: subscribe reimp-mig-tf in the body of your message. As for the db-beta mailing list, this is a moderated mailing list so some delays and so some delays in subscription are possible. If you have any other questions or comments, please contact <ripe-dbm(a)ripe.net>. Regards, A. M. R. Magee ______________ RIPE NCC

Plan of the migration to the new RIPE Database
by Andrei Robachevsky 02 Apr '01

02 Apr '01

Dear Colleagues, [apologies for duplicate messages] Please find below a list of milestones related to the migration to the new version of the RIPE Database. Your comments and suggestions are welcome. Should you have any further question regarding the migration, please don't hesitate to contact me. Best regards, Andrei Robachevsky DB Group Manager RIPE NCC ------------------------------------------------------------------ Date Actions ------------------------------------------------------------------ 4.04 Final release of the v3.0 DB software 12.04 Advised mirror's switchover to rpsl.ripe.net. - Reminder is sent to NRTM clients on 9.04 - Starting from this date NRTM clients that mirror the RIPE Database are advised to use the new server at rpsl.ripe.net, port 4444 for mirroring. 17-18.04 Migration of the TEST database to v3.0 (RPSL) - TEST Database becomes a RPSL database. Updates are accepted in RPSL format at <test-dbm(a)ripe.net>. - No RIPE-181 TEST database exists anymore. - Estimated downtime 6 hours. 22.04-23.04 Migration of the RIPE Database to v3.0 (RPSL) - New server becomes the official RIPE Database server at 00:00 23.04. - Updates received after 16:00, 22.04 are queued until the new server becomes operational. After that they are automatically converted to RPSL and processed by the new server. New syntax and authorization rules apply. - Downtime in queries will be deliberately introduced to mark the migration. Whois server downtime is planned from 18:00, 22.04 till 00:00 23.04. During this time a message explaining the migration process will be sent as a whois query reply. 23.04, 00:00 New server becomes the official RIPE Database server - Short (1-2 min) downtime is possible during final tests. 23.04, 02:00 New server starts processing updates - Two mail robots are available: <auto-dbm(a)ripe.net> - updates in RIPE-181 format (restrictions apply) <auto-rpsl(a)ripe.net> - updates in RPSL format (recommended).

The Cidr Report
by Tony Bates 31 Mar '01

31 Mar '01

This is an auto-generated mail on Fri Mar 30 23:00:00 PST 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.
