Anti-Spam Working Group


  • Adiel Akplogan, CEO AfriNIC, noted that he was part of the Internet Governance Forum (IGF) Advisory Group. He invited any volunteers from the Anti-Spam Working Group who wanted to be part of the panel in the forthcoming IGF Workshop on spam to contact him or the RIPE NCC and provide a brief resume. The Workshop will take place during the next IGF Meeting in Athens, 30 October – 2 November 2006.
  • Adiel also called for experts interested in providing a tutorial relevant to issues associated with spam, phishing and e-mail security at the forthcoming AfriNIC Meeting, to be held from 27 November – 1 December 2006 in Mauritius.


  1. Consensus has been achieved for publishing an updated version of ripe-206 'Good Practice for Combating Unsolicited Bulk Email'. Rodney Tillotson, Anti-Spam WG Chair, will direct the RIPE NCC to publish the updated version of this document, and will send a request to the Anti-Spam Working Group for volunteers to work on future revisions to this document.

Database Working Group


  • A very interesting discussion, concerning ASN32 incorporating advice and input from Geoff Huston was held. He urged the WG to start thinking about AS32 now, and consider the very likely operational impact, even if the attendees continued to use ASN16 numbers themselves.


  1. AP53.1: WW144 reformulate the proposal to make the country attribute optional and multiple for inetnum and inet6num objects and post to the mailing list.
  2. AP53.2: RIPE NCC to check and point out this requirement to various software developers, including but not limited to: irrtoolset, quagga etc.
  3. AP53.3 RIPE NCC to make sure that if there is a "flag day" for ASN32 behaviour then the planning and introduction for this is done properly and advertised appropriately.
  4. AP53.4: WW144 alert Routing WG about the implications of the ASN16 to ASN32 transition on tools.
  5. AP53.5: WW144 wait for the formal consensus of the ENUM WG (to change the NON-REGISTRY attribute on organisation objects to OTHER) and then ask the RIPE NCC to make the change.

DNS Working Group


  • There was lively discussion of Duane Wessels' plenary presentation, especially on the question of encouraging TCP as a preferred transport for DNS to counter some of his "open issues". Most people agreed that there is a need to catalogue the various best current practice documents in the world of DNS operation.
  • Various software vendors and Internet organisations gave updates on latest developments around the DNS, focusing on the security of the DNS and DNSSEC availability and deployment.


  1. Several open action items were closed successfully, pending mailing list approval. This includes work on AAAA record anomalies in name servers and the RIPE NCC's work on lame delegations and the DNSSEC deployment in the reverse tree.
  2. The question of regular lameness checks in will be addressed by a task force formed in cooperation with the ENUM Working Group. A report is due at RIPE 54.

EIX Working Group


  • Greg Hankins from Force10 Networks gave an update about higher speed Ethernet
  • Elisa Jasinska from AMS-IX gave a presentation about the implementation of sFlow software at AMS-IX.
  • Serge Radovcic (Euro-IX Secretariat) presented an update about Euro-IX which included statistics gathered from all known IXPs in Europe.
  • There were eight short IXP update reports from AMS-IX, NDIX, DE-CIX, VIX, LINX, MIX, NIX.CZ and NETNOD.


  1. Input for the IXP Switch wishlist will be sent to the EIX mailing list. A new draft will be posted on the mailing list by Mike Hughes. Hopefully the document will be adopted during RIPE 54.
  2. Mike Hughes will request a schedule change in the meeting plan at the WG Chairs' meeting. He will try to get the two hour block on Wednesday afternoon, because the 90 minutes of the current session is regularly used up.
