27 Feb '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [Apologies for duplicate mails] Dear All, The Inter-Domain Routing Workshop will take place at the RIPE NCC in Amsterdam during the weekend before RIPE 48 (May 1-2, 2004). This RIPE meeting will also be held in Amsterdam. The goal of the workshop is to bring together a focused group of operators, vendors, and researchers to discuss important mid- and long-term operational problems, as well as new academic ideas, in an OPEN forum. The wide scope for topics was intended on our part. The organisers are: * Intel Research * Universität Karlsruhe Institut für Telematik * Technische Universität München, Computer Science Department * RIPE NCC * Schlund+Partner AG, Karlsruhe See URL for more information: http://www.tm.uka.de/idrws/ We are hoping that these discussions will become an invigorating and lively affair. Please feel free to drop us a line at idrws(a)ripe.net.

Because they are being filtered :-) If more people filtered bogons, the "ROI" would be even lower. Although it is clear that bogon filtering is not a complete cure for spoofing, it does help and it also helps for some spammers. The only negative effect of bogon filtering is not-up-to-date filters, which is why we have written this draft that will expand the applicability domain of bogon route servers and other filtering schemes.

>The RIPE NCC has prepared a draft document titled "De-Bogonising New >Address Blocks": That is a misleading title. The problem is that ISPs cannot react quickly enough to open filters when new ranges are allocated. The proposed solution is to provide advance notification. I suppose this could allow ISPs to open filters before the new addresses are actually in use officially. However, it will also allow spammers to announce this space and get it through bogon filters. The real solution to this problem is to make it possible for ISPs to closely track RIR allocations in their filters in a semi-automated way. There may still be a few days of delay before a new allocation is fully routable but ISPs can compensate for that with internal processes. Why can't ISPs subscribe to a feed of all new RIPE allocations in near real-time? --Michael Dillon
