Deaggregation by large organizations

Some hours ago Iljitsch van Beijnum posted an email with the above subject to the RIPE Best Current Operational Practices (BCOP) mailing list.
Therein he describes the growing issue of (IPv6 prefix) deaggregation desires/approaches by certain organizations vs. the filtering practices of other organizations (providers). I touched this problem, from an enterprise’s perspective, some time ago in the second part of my blog post series on IPv6 address planning. Given we think that the discussion is heavily needed from several angles, I had actually submitted a talk on the topic twice (for the RIPE meeting in Warsaw in May and the upcoming one in London) which was unfortunately rejected at both occasions.
I’m hence very happy to see that a dialogue about the inherent dilemma might be started by Iljitsch’s mail. As a contribution to the development of a BCOP document I will hereby publish our draft slides of the talk which was initially planned. Furthermore two fellow IPv6 practitioners (Hi Roland & Nico!) and I plan to release a detailed paper with research results as for IPv6 prefix distribution at major European IXs in the near future.

Let’s hope that we as the IPv6 community can reach some consensus in this space soon. See you in London,
have a good one everybody

  1. Enno – Nice blog and great links. The presentation is also good. My two cents is I don’t think the IETF or RIRs will take this on. My gut feel is this will be fleshed out over the next couple years in *NOG hallway conversations. Wish I could give you something more definitive but I agree with Gert’s conclusion, “well, today (what I have shown you) is likely to work, but it might stop working tomorrow, and there is no document that you could show around to those that break your connectivity to show them that ‘you are doing the right thing'”. If anything, the more I look into it the more I find conflicting opinions. As you noted in previous posts, it gets especially interesting when you have a large multi-national with a major presence in multiple RIR-regions and you’re trying to develop a consistent global policy.
