In fact, I tried to rescue ULA-central by means of having the support in RIR policies (see pointers below). It didn't reached consensus at that time, but new arguments, new experience may change the situation (it happened already several times with other policy proposals). After we get that, we can advance draft-ietf-ipv6-ula-central. If we think this is a possible path, I'm happy to work again in the ULA-Central policy proposals in the 5 RIRs. https://www.ripe.net/participate/policies/proposals/2007-05 https://www.apnic.net/community/policy/proposals/prop-048/ https://afrinic.net/policy/archive/proposal-for-ipv6-ula-central-afpub-2007-v6-003 https://www.lacnic.net/innovaportal/file/556/1/lac-2007-06-sp.pdf I can't find the ARIN one, not sure if I presented it there as well. Regards, Jordi El 30/5/19 3:13, "ipv6 en nombre de George Michaelson" <ipv6-bounces@ietf.org en nombre de ggm@algebras.org> escribió: point of information. the RIR system exists, and in the ULA discussions it was understood that globally unique assigned address processes were RFC bound in RFC2050 and subsequently RFC7020. If it becomes necessary to implement the service, the RIRs already indicated they understood how to manage ULA distribution with uniqueness, and mechanisms to apply normal address services like WHOIS. I guess I'm saying "just because we don't, doesn't mean we can't" -G On Thu, May 30, 2019 at 11:08 AM Mark Smith <markzzzsmith@gmail.com> wrote: > > On Thu, 30 May 2019 at 10:58, Toerless Eckert <tte@cs.fau.de> wrote: > > > > I cant brainstorm a lot more without more details of what you're > > trying to achieve, and therefore what the constraints are. > > > > Worst case, you float the idea to a single ULA prefix defined > > by your RFCs mecanism and see how reviewers like this.
