I would support Paul proposal, but with one small change. Paul proposes a delegation hierarchy in the ULA-C space:

Call in it RIR assumes that the numbers can only be allocated by the current set of regional registries. I don't see any technical reason to carve this policy in a standard. I would much prefer a neutral designation, e.g. "Registry Number". -- Christian Huitema -------------------------------------------------------------------- IETF IPv6 working group mailing list [email protected] Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
