by Emilio Madaio 25 Feb '11

25 Feb '11

[Apologies for duplicates. Courtesy copy sent to Routing Working Group and RIPE NCC Services Working Group. Please direct feedback to the Address Policy Working Group mailing list.] Dear Colleagues, The new version of RIPE Policy Proposal 2008-08, "Initial Certification Policy for Provider Aggregatable Address Space Holders", was published on 9 February 2011. The time period for community review ends on 23 February 2011. Some feedback was sent to the Address Policy Working Group mailing list. However, to maintain the discussion, we strongly recommend that you share your ideas and comments and clearly let the community know if you: - Support the implementation of the proposal - Support the general principle of the proposal but would prefer another wording - Support the general principle with some details changed but agree to postpone this discussion until another stage of the policy proposal review. (This is an initial proposal that covers only PA resources. If the community supports extending certification to all resources, then another version of the proposal will be necessary.) - Do not support the proposal (please explain your motivations) You can find the full proposal at: http://www.ripe.net/ripe/policies/proposals/2008-08 and the draft document at: http://www.ripe.net/ripe/policies/proposals/2008-08/draft Please send an email with your comments to address-policy-wg(a)ripe.net by 23 February 2011.

Implementation of "pingable:" attribute in the RIPE Database
by Denis Walker 21 Feb '11

21 Feb '11

[Apologies for duplicate emails] Dear Colleagues, The RIPE NCC has implemented the "pingable:" and "ping-hdl:" attributes according to the specification in RFC 5943. They can now be used in ROUTE and ROUTE6 objects in the RIPE Database. RFC 5943 describes the syntax and explains how to use them: http://tools.ietf.org/html/rfc5943 The "pingable:" addresses are already active for beacons, anchors and debogon routes announced by the RIPE NCC Routing Information Service (RIS). For an example of how these are announced, see the ROUTE object for 84.205.81.0/24. For more information about RIS beacons and anchors, please see: http://www.ripe.net/data-tools/stats/ris/ris-routing-beacons Regards, Denis Walker Business Analyst RIPE NCC Database Group

Three Case Studies on the Egyptian Disconnection
by Mirjam Kuehne 15 Feb '11

15 Feb '11

[apologies for duplicates] Dear colleagues, Claudio Squarcella from Roma Tre University presents three analyses related to the recent events in Egypt, proving interesting behavior in relation to the observed disconnection. He used tools like BGPlay and iBGPlay, developed for the visualisation of BGP dynamics. See his findings on RIPE Labs: http://labs.ripe.net/Members/csquarce/three-case-studies-egyptian-disconnec… Kind Regards, Mirjam Kuehne RIPE NCC
