Dear all, This is to inform you that the RIPE NCC has recently been allocated the CIDR blocks 80/8 and 81/8 by IANA. The RIPE NCC is currently starting to make allocations primarily from 80/8. The minimum allocation size made by the RIPE NCC in these address blocks is a /20. ** If you use prefix based filtering in your routers, please note this change ** This has been announced previously but may not have reached all affected parties. We sincerely apologise for this. For a complete list of all /8 address blocks, please refer to: http://www.iana.org/assignments/ipv4-address-space Kind regards, Nurani Nimpuno +------------------------------------+ | Nurani Nimpuno | | Registration Services Manager | | RIPE Network Co-ordination Centre | | http://www.ripe.net | +------------------------------------+

Hi all, we currently experience heavy routing/performance problems to US networks. These are located beyond our upstreams Big sites as hp.com are hardly reachable, these problems can be found on the MAE-East looking glass as well. Is anybody aware of these problems and the reasons?

RIPE-181 to RPSL Migration; Phase 2.
by DB-News 10 May '01

10 May '01

Dear Colleagues, (Apologies for multiple messages). On and from Monday, 14th May, 2001, <auto-dbm(a)ripe.net> shall only accept updates in RPSL format; updates in RIPE-181 format will no longer be accepted. Updates in RIPE-181 format can be sent to <auto-181(a)ripe.net>, where they will be automatically converted to RPSL format. <auto-rpsl(a)ripe.net> will continue to accept updates in RPSL format. The update path for the TEST database will also be changed. In summary, from 14th May, 2001: =============================== RIPE Database: - ------------- <auto-dbm(a)ripe.net> - updates in RPSL format only <auto-rpsl(a)ripe.net> - updates in RPSL format only <auto-181(a)ripe.net> - updates in RIPE-181 format, automatically converted to RP S L format TEST Database: - ------------- <test-dbm(a)ripe.net> - updates in RPSL format only <test-rpsl(a)ripe.net> - updates in RPSL format only <test-181(a)ripe.net> - updates in RIPE-181 format, automatically converted to RP S L format On Monday, 14th May, 2001, we cannot guarantee that an update message sent to <auto-dbm(a)ripe.net> will use a specific update path (RPSL or RIPE-181). Thus, we advise that updates in RIPE-181 format should be sent to <auto-181(a)ripe.net> and that updates in RPSL format should be sent to <auto-rpsl(a)ripe.net>. Please note that from Monday, 15th October, 2001, updates in RIPE-181 format will no longer be accepted by the RIPE Database. Further information is available from http://www.ripe.net/rpsl/. If you have any questions, please contact <ripe-dbm(a)ripe.net>. Regards, A. M. R. Magee - -------------- Database Group RIPE NCC

The Cidr Report
by Tony Bates 05 May '01

05 May '01

This is an auto-generated mail on Fri May 4 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.
