2005-01 HD-Ratio for IPv4
2005-02 IP Assignments for Anycast DNS
2005-03 IPv6 Initial Allocation Criteria
2005-08 Amend IPv6 Assignment and Utilisation Requirements
2005-12 4-byte AS Number Policy
2006-01 Provider Independent (PI) IPv6 Assignments for End User Organisations

Anti-Spam Working Group


  • Considered updating RIPE 206, BCP for ISPs on preventing UBE from their own networks. There was agreement to start the RIPE Policy Development Process (PDP) with the draft document.
  • Support was given to requests from the DB WG to confirm the status of IRT objects, "abuse-mailbox:" attributes and default whois output.

Database Working Group

Action Points:

  • A call will be made for a task force to be created to help the RIPE NCC update the RIPE Database to comply with relevant Data Protection legislation.
  • The RIPE NCC is to send its proposal to support ENUM delegations using the nserver: attribute to the WG-DB and DNS-DB mailing lists.
  • The irt: proposal will be reformulated and posted to DB-WG mailing list.
  • The RIPE NCC is to produce statistics showing how many objects are only protected by CRYPT-PW.
  • The RIPE NCC (and Peter Koch) will produce a proposal, with timescales, for removing WW144 + CRYPT-PW and circulate it on the mailing list.

DNS Working Group

Action Points:

  • The RIPE NCC was asked to investigate and document the effects of lameness on DNS.
  • The community is to work further on a proposal to bring ENUM Zone Management in line with the reverse DNS.


  • There was general praise for the way in which the RIPE NCC had operated K-root. Plans to develop this service further were welcomed.

EIX Working Group


  • There were twelve IXP update presentations.
  • Mike Hughes asked the attendees to let the WG Chairs know of presentations that are longer than two minutes at least three months before the next RIPE Meeting so that they may ask the meeting coordination for a longer WG slot.

ENUM Working Group

Action Points:

  • The RIPE NCC is to expand the server statistics to include other servers than just those of the RIPE NCC.
  • Carsten Schiefner is to stimulate discussion on the mailing list about the format of the communications documentation on the site (currently .zip).
  • The RIPE NCC is to follow up on the missing links reported by Carsten Schiefner (after the statistics in the first action point above have been expanded).

IPv6 Working Group

Action Points:

  • The RIPE NCC was asked to revise the acronym list in the meeting pack to remove obsolete terms, such as NLA and TLA.
  • The RIPE NCC was asked to create a link from the IPv6 WG page to the APNIC events page.
  • The RIPE NCC was asked to provide traffic reports on IPv6 usage during RIPE Meetings.


  • The group discussed the winding-down of the zone. It was decided that the RIPE NCC should proceed as planned and remove the delegations on 1 June.
  • The group discussed the future directions of the WG. General consensus was that there is work to be done on the IPv6 allocation policy, and that effort needs to be made to find operators willing to present deployment experiences at the WG sessions.

RIPE NCC Services Working Group

Action Points:

  • The RIPE NCC was asked to circulate a paper about the open issues regarding resource certification on the mailing lists to get the discussion started.

Routing Working Group


  • Rob Evans volunteered to be the Routing WG Co-Chair. The WG welcomed him in this position.
  • There was consensus to update RIPE 229. Phil Smith gave an update about it and a new RIPE document will be published.
  • A discussion was started on the desired authorisation mechanisms to be used in the Internet Routing Registry.

Test Traffic Working Group

Action Points:

  • The RIPE NCC is to create a mailing list with a public archive for the task force on the direction of TTM.


  • Andrei Robachevsky, RIPE NCC Chief Technical Officer, presented the RIPE NCC's ideas on the future direction of the Test Traffic Measurements (TTM) service. A small task force (consisting of Brian Nisbet, Geert Nijpels, Niall O'Reilly, Daniel Karrenberg, Henk Uijterwaal and Andrei Robachevsky) was created to help move these ideas forward.
  • The proposal for multicast measurements with TTM was discussed. It was agreed that this could wait until the transition of TTM to a new model and new architecture has been completed.
  • The proposal for Consumer Broadband Measurements (CBM) was discussed. It was agreed that before creating a new RIPE NCC service, a pilot implementation should be done; a proof of concept with limited scope that shows what people can expect from a CBM service.

Webcast, Podcast and Remote Feedback Archives

During RIPE 52, feedback was collected from remote participants via IRC and Jabber. All webcasts, podcasts and IRC/Jabber feedback is archived.
