[Apologies for duplicate emails] Dear Colleagues, A short summary of Tuesday's events at RIPE 63 can be found below. The full Daily Meeting Report, including photos, links to presentations, webcasts and further information, can be found at: http://ripe63.ripe.net/programme/report/tuesday/ Plenary Day two of RIPE 63 began with a busy Plenary session, with talks on "DDoS Attack Trends Through 2009-2011", the "Reputation of Networks – RIPE Region" and "Operational Experiences in Deploying 100 GbE". The RIPE NCC talked about "IPv4 and IPv6 assignments for RIPE NCC Routing Information Service" and "Resource Request for Business Operations". There were several comments from the audience about this and it was left to the community to decide the outcome during the Closing Plenary on Friday. The second Plenary session continued the focus on technical issues, starting with a presentation on transit costs, followed by BGP policy violations in the data-plane, and an analysis of IPv6 latencies. A study of measured trends in IPv6 adoption looked primarily at trends seen around and following World IPv6 Day. The third Plenary session saw RIPE NCC's Managing Director, Axel Pawlik, share the RIPE NCC's plan for contacting legacy space holders in the RIPE NCC service region. The presentation prompted a lot of participation from the audience, many of whom were legacy space holders themselves. Axel encouraged legacy space holders, even those with particularly specific situations, to contact the RIPE NCC. RIPE Chair, Rob Blokzijl, supported the efforts to "blow off the dust" of legacy address space. IPv6 remains a hot topic at RIPE Meetings, with a talk on "IPv6 Deployment Beauty Pageant" and a four-person panel discussing "CPE and End-User IPv6". Audience comments indicated that having hardware providers speaking about IPv6 deployment was an encouraging indication that things were moving in the right direction. Next, several interesting Lightning Talks were held and David Kessens, reported from a draft document currently reviewed by the IETF: IANA Reserved IPv4 prefixes for shared CGN space and urged everyone to look at the draft and participate in the discussion. At the end of the session, Marco Hogewoning, WG co-Chair, introduced 'speed dating' between those who have deployed IPv6 and those busy deploying it. IPv6 Working Group Shane Kerr, ISC, gave a presentation on renumbering for enterprise networks and the IETF Working Group that has been established to look at this issue, seeking operator feedback on their work. The update to RIPE Document, ripe-501, "Requirements for IPv6 in ICT Equipment", which will conclude its Last Call phase next week, was discussed. Constanze Bürger delivered an update on the German government's roll-out of a federal IPv6 network, which led to some discussion and Timo Hilbrink provided an update on the IPv6 deployment of Dutch ISP XS4ALL. Anti-Abuse Working Group There was a good mix of the technical, the practical and the policy at the Anti-Abuse Working Group session. Joao Damas, ISC, gave an interesting presentation on passive DNS. Laura Cobley, Customer Services Manager at the RIPE NCC, spoke about how to report abuse to the RIPE NCC. She received many helpful suggestions on how the process should work. Michele Neylon, Blacknight, talked about how hosting companies deal with abuse. The session ended with lengthy discussion on interactions with governments and legal enforcement agencies.
