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

Announcement Routing Registry Training Courses
by RIPE NCC Training 04 Oct '04

04 Oct '04

Dear Colleagues, [apologies for duplicate postings] As a service to its members the RIPE NCC offers the "Routing Registry Training Course". The main objective of the "Routing Registry Training Course" is to familiarise the LIRs with the features of the Routing Registry, while introducing the relevant tools and services of the RIPE NCC. The course also offers practical exercises. OVERVIEW OF TOPICS COVERED IN THE COURSE: - Routing Registry as a part of the RIPE Whois Database and the Internet Routing Registry (IRR) - Specifying routing policies using (RPSL) Routing Policy Specification Language and the RtConfig tool - IRRToolSet - Routing Information Service (RIS) - Routing Registry Consistency Check Project Please note that this is an advanced course. It will: - NOT teach the basics of routing - NOT teach the basics of RIPE Database operations, - NOT describe how to receive Internet resources from the RIPE NCC - NOT describe how to operate a Local Internet Registry (LIR) The target audience of the course are technical staff of LIRs: e.g. network operators, engineers etc. This course is not intended for administrative or management staff (e.g. Hostmasters) . It is assumed that all attendees will be familiar with Border Gateway Protocol routing and with the RIPE Database (i.e. creating/modifying objects). This course is based on interactive exercises in a local network set-up. Please bring your laptops equipped with the following: - A working Ethernet card, - Three meters of Ethernet cable, - A secure connection client, - A web browser. Please be prepared to share your laptop (or at least allow another attendee to "look over your shoulder") if necessary. The Routing Registry Training Course is conducted in the English language and is free of charge, since it is covered by the membership fee. More information about the Routing Registry Training Course can be found at: http://www.ripe.net/training/rr/ REGISTRATION: You can register for a Routing Registry Training Course at the following URL: http://www.ripe.net/cgi-bin/trainingform.pl.cgi Or by completing the registration form at the end of this e-mail and replying to <training(a)ripe.net> . In order to register for a Routing Registry Training Course you must be an employee of an LIR and either: - be an LIR contact - be confirmed by an LIR contact LIR contacts are those employees of an LIR who are registered with RIPE NCC as authoritative contact persons. It is expected that most of those interested in the Routing Registry Training Course will not be an authoritative contact person for their LIR, and therefore will be, refused by the course registration "robot". In order to be admitted to the course, a confirmation e-mail must be sent to <training(a)ripe.net>. Please approach the LIR contacts from your organisation personally, since the identity of LIR contacts is confidential, and the RIPE NCC is unable to divulge contact persons for any given LIR.
