Hi APWG, one of the issues pointed out by Alex le Heugh from the RIPE NCC RS department at the last RIPE meeting was the "80% rule" for additional IPv4 allocations, which has multiple, contradictory definitions in the current address policy documents. See here: http://www.ripe.net/ripe/meetings/ripe-59/presentations/leheux-rough-edges-o... on page 17-21 and http://www.ripe.net/ripe/docs/ripe-484.html, section 5.3 and 5.4 The different sections of the policy text both describe the rule slightly differently. This makes it unclear how the 80% rule should be applied. Let me explain by example: - a LIR has a /16, which is at 95% utilization, and a /19 that is at 40% utilization. Over all their address space, the utilization would be 88%. - interpretation 1: "if a LIR holds multiple allocations, every *single* of them needs to be filled by 80%" would result in "the LIR will not get a new allocation, because the /19 is only at 40%" - interpretation 2: "if a LIR holds multiple allocations, the grand total of them needs to be filled by 80%" would result in "the LIR *will* get another allocation, because they have used 88%". Personally, I think that the interpretation according to 5.3 of the IPv4 address policy document ("interpretation 2") is the intention of the policy. 5.4 (sub-allocations) was added later, and has language about the 80% criteria that is misleading - this section is only concerned about sub-allocations, and "the 80% sentence" was put in there to emphasize the existing rule, not to change it (I know that from the proposer of this policy change...). Now, "just changing the text according to what the WG chair thinks" would not be the right thing - so what I think is the way forward now is to get feedback from *you*, and if there is clear guidance from the working group on resolving this ambiguity, we run a formal proposal to change the wording of the document in one way or the other. (Please don't get into sidetrack discussions on whether "80%" or "IPv4" is useful, but focus on this specific question.) thanks, and regards, Gert Doering, APWG Chair -- Total number of prefixes smaller than registry allocations: 144438 SpaceNet AG Vorstand: Sebastian v.
