IRRToolSet maintenance moved from RIPE NCC to ISC
by Shane Kerr 17 Dec '04

17 Dec '04

Colleagues, We are happy to announce that the maintenance for the IRRToolSet has moved from the RIPE NCC to the Internet Systems Consortium (ISC). Starting now, ISC will support software development and maintenance of this suite. The new web page for this is: http://www.isc.org/sw/IRRToolSet/ The mailing list has been moved. The new address is <irrtoolset(a)isc.org>. E-mail will be forwarded from the existing mailing list (*). The RIPE NCC believes that ISC's software development model matches the IRRToolSet requirements, and that ISC will be a better home for the software. Operators and developers will have a set-up that is more typical to collaborative open source software, from a company that is experienced and focused on it. The RIPE NCC is grateful to ISC for agreeing to maintain this useful set of tools. We will continue to provide support for RIPE-specific portions and work with ISC in refining the software. -- Shane Kerr Software Manager RIPE NCC (*) When the mailing list forwarding began, Thursday 2004-12-16, filtering was removed. Shortly after the mailing list filtering policy was changed to "subscriber only". Apologies for the unwanted mail received during this period.

RE: The Cidr Report

Interestingly enough what Covad appears to be saying is: If we had a way to announce two things 1 - here are the advertisements for covering aggregates for Covad AND 2 - do not believe any more specifics for these address blocks, as they are NOT part of Covad's routing policy for these prefixes then we would not be seeing this unfortunate case of unauthorized route leakage being resolved in a way that seems to have unfortunate bgp implications in terms of more specifics appearing. So its an interesting question. How could Covad achieve a routing policy announcement of the form as stated in 2 above? regards, Geoff

I've been secretly hoping no one would notice Covad's ascension to the number one spot (which we've held for well over a month now ;). I actually made it through the last NANOG without a single mention of Covad's route bloat! There are no mistakes or excuses here. And there's definitely no renumbering going on. We were actually fully aggregated until an unfortunate incident this past May involving a distant service provider leaking our specifics. Gigs of traffic somehow vanished into Eastern Europe. The net result was deaggregation. It's unlikely we will aggregate down to less than 10 netblocks again. However, we do make every effort to aggregate where possible. Our superblocks are also being advertised, for those of you that want to filter our routes. Want to discuss further? Great. Call me or email me directly. Contact info is below. Think you can do it better? Even better. It turns out I'm hiring. :) Regards, Brad -- Covad Communications 408-434-2048 broldan(a)covad.com
