As people who don't ULA don't have to use it (and filter fc00::/7),
ULA (RFC4139) is fd00::/8. These are already standardized and accepted and can be automatically generated by anyone. RIR's have no involvement in ULA's at all. Tool for generating ULA's can now be easily found at: http://www.sixxs.net/tools/grh/ula/ Which also contains a 'registry', to 'register' the ULA one is using. This is an intermediate step to ULA-Central. Anybody can generate a prefix and register them in that list. Of course people can simply ignore that list if they want/do not know about it as it is not official in anyway. In that respect, there are some newly started discussions in the IAB about this and on how to move forward with a possible ULA-C scheme. If somebody wants ULA-Central, then, as Fred Baker indicated, use the IETF IPv6 Working Group mailinglist and raise your voice there. When there is again a ULA-Central draft, and then an RFC, then this can be brought forward to the RIR's and am fairly sure that they can then apply a proper policy for it. When there is no such RFC though all of that is useless. My personal stance on all the ULA/PI/PA stuff: RIR's should provide a means to let an organization get a block of size X, where X depends on the size they can justify to the RIR. Greets, Jeroen PS: I heared another rumor that IANA might at one point have a similar "Registered" ULA list, when that happens, the one at SixXS will cease to exist and a redirect will be made to IANA. The list will of course be passed to IANA so that they can build further upon that. The generation function of course will always stay there so that it will be easy to find.
