[Apologies for duplicate emails] Dear colleagues, A short summary of Thursday'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/thursday/ Address Policy Working Group The third AP WG session started on Thursday with discussion on the IPv6 PI/PA unification proposal made by Gert Doering, AP Working Group co-Chair. There was an analysis of special cases, the costs and the "multiple blocks per LIR" scenario that would result from the unification. The RIPE NCC was tasked to look into possible reasons why LIRs would like to be able to request multiple prefixes. More feedback was encouraged on the mailing list. During the Open Policy Hour, the recent RFC 6382, published by the IETF, was presented. Some possible interpretation issues with the ripe-525 policy, "Autonomous System (AS) Number Assignment Policy" were highlighted. The attendees present reached the conclusion that a policy proposal should not be submitted. DNS Working Group The first session of the DNS Session WG had a very diverse set of presentations, ranging from an update by the RIPE NCC, an update on the DANE work in IETF, to DNS configuration management and two different implementations of an authoritative DNS server. The second DNS session started with an interesting presentation about the excessive increased query load on the root name servers that occurred for a brief time this summer, followed by a presentation on "DNSSEC Trigger". There was also an update on the "IDN Variant Issues Project" and an update on the status of the DNSEASY and SSR Meetings. The session ended with a very engaging panel discussion, ranging from the technical to the political implications of blocking or rewriting DNS query results at the registry or ISP level and how that affects operators throughout the world. EIX Working Group The first presentation of the session was an introduction to the local peering scene in Austria, given by Christian Panigl, VIX. There was then an update on EIX activities, which included the new IPv4 policy and switch wishlist. Remco van Mook, Equinix, and Martin Pels, AMS-IX, offered to help with the document. The session continued with a presentation on "Monitoring Platforms for Internet Exchange Points" and "Jumbo Frames in AMS-IX", which prompted many in the audience to voice their opinions. The second EIX WG session began with a presentation on "Extended Communities for Route-Servers and ASN32", followed by "How to Resolve Edge Redundancy for Peering". Next up was Joao Damas, ISC, who talked about the Open Source Routing project he was working on. There were two presentations on problems experienced with Proxy-ARP and discussion focused on why this happened. A Cisco representative said he would bring this feedback back to Cisco. The session ended with on open mic session of lightning updates. RIPE Database Working Group The RIPE NCC shared the latest RIPE Database developments. RIPE NCC staff members, Kaveh Ranjbar and Denis Walker, presented on the action points from the RIPE 62 Meeting, all of which have been completed. The main discussion of the session was about the geolocation service. The RIPE NCC showed a prototype of the service and the WG Chair will present the proposed way forward on the RIPE Database mailing list. The RIPE NCC was also requested to investigate how internationalisation could be made possible and what would need to be done if it is decided to fully serve the data in utf-8. As reported in the Anti-Abuse WG earlier this week, a requirement of an abuse contact i in the RIPE Database will start the PDP in the coming weeks.. This is the result of the Abuse Contact Task Force. An other issue raised was that objects sponsored by an LIR are not shown in the RIPE Database. The mailing list will be used to analyse how to move forward. Cooperation Working Group The RIPE Cooperation Working Group met in the final session of the day, and included a remote presentation from European Commission representative Andrea Glorioso, who emphasised the need for more synchronisation between the RIPE community and the Commission. Chris Buckridge, RIPE NCC, gave an update on the Internet Governance Forum 2011, while Nurani Nimpuno, Netnod, spoke about the work of the United Nations CSTD Working Group on "Improvements to the IGF". MAT Working Group The session started with NIC Brazil reporting on how RIPE TTM data is being used in real time in Brazil. Next there was a presentation on Google's "Measurement Lab (M-Lab)" . After the talk, a number of people asked if Google was considering integrating or sponsoring RIPE Atlas. Wolfgang Nagele, RIPE NCC, then presented on "PCAP Analysis with HADOOP". The session concluded with two presentations by the RIPE NCC, one of which updated the audience on the recent developments in the RIPE NCC's measurements activities. The other announced the introduction of user defined measurements for RIPE Atlas. David Freedman, Claranet, then asked the audience how the reachability of a prefix could be measured so that people can build filters properly and proposed an experiment. Interest was expressed and he said he would formulate a more solid proposal. IPv6 Privacy BoF An IPv6 Privacy BoF was held in the Park Congress I room following the last working group sessions of the day. The German NGO Arbeitskreis Vorratsdatenspeicherung’s (Working Group on Data Retention) position on how user privacy should be supported by ISPs and software/hardware vendors was discussed as well as how privacy concerns will influence ISPs’ IPv6 assignment practices.
