Owen, I just want to be clear about somehting you said. You view ULA central as "an end-run on the RIR process." Is this because the expired ULC-central draft suggests that some new "central allocation authority" be established to assign these addresses? If the draft RFC was resurrected and all references to "cental allocation authority" and "cental authority" were removed and replaced with clear text explaining the following: - IANA should divide FC00::/8 into eight /11s - Each RIR would be given one /11 to make ULA-Central assignments - Three /11s would be held in reserve for new RIRs in the future. Would you still think this was an end-run on the RIR process? Would you be in support of the draft moving forward? Do you think this should not be decided by an RFC, but rather as a global policy through each of the RIRs? If you prefer the RIR process, would you be in favor of a global policy submitted to ARIN that had the provisions of the expired ULA-central draft, with the modification of removing "cental authority" and clearly designating how IANA should divide the space among the existing RIRs? ULA-central text snippets below. ___Jason draft-ietf-ipv6-ula-central-01.txt -- section 3.2.1 "Global IDs should be assigned under the authority of a single allocation organization because they are pseudo-random and without any structure. This is easiest to accomplish if there is a single authority for the assignments." draft-ietf-ipv6-ula-central-01.txt -- section 7.0 "The IANA is instructed to designate an allocation authority, based on instructions from the IAB, for centrally assigned Unique Local IPv6 unicast addresses. This allocation authority shall comply with the requirements described in Section 3.2 of this document, including in particular allocation on a permanent basis and with sufficient provisions to avoid hoarding of numbers. If deemed appropriate, the authority may also consist of multiple organizations performing the allocation authority duties. The designated allocation authority is required to document how they will meet the requirements described in Section 3.2 of this document in an RFC. This RFC will be shepherd through the IETF by the IAB." ========================================================================== Jason Schiller (703)886.6648 Senior Internet Network Engineer fax:(703)886.0512 Public IP Global Network Engineering schiller@uu.net UUNET / Verizon jason.schiller@verizonbusiness.com The good news about having an email address that is twice as long is that it increases traffic on the Internet.

ULA Central is intended so that some subset of the internet can reliably use it to interconnect while not being "globally" routed.
The problem I have with this theory is that the delta between a collection of networks routing by mutual agreement and the internet is:
A. Fuzzy B. Non-Existant C. There is no difference D. Meaningless E. Any and/or All of the above
Pick your favorite answer from the above and you've pretty much got it. If ULA central were limited to not exiting the local AS (in some meaningful way, like routers won't forward routes or traffic to ULA addresses to external adjacencies), then, I might see it as something other than an end-run on the RIR process. However, in it's current state of "license for anyone who wants to run a competing RIR for networks that choose to interoperate on this basis" I think it's a pretty bad idea.

I don't understand your point about why ULA need to be registered if its not going to be globally routed. Also PI is not the same as ULA - PI do come from RIRs and in IPv6 there was no way to get PI (except in a few special cases) until recent ARIN's micro-allocation policy.

I agree that this will help inform the debate, and while Iljitsch did a good job of outlining the issue, he left out a significant point::: People explicitly chose to be in the state of "as there is currently no obvious way to make services only available locally" by insisting that the local-scope addressing range have a global-scope as far as application developers were concerned. Now the application developers are complaining about the consequences of their choice, because the alternative to 'no routing path for an attack' is to insert a device that has to make policy decisions with limited information.
The current ULA-central discussions will be directly involved in this issue. It is critical that all of the RIR's have policies establishing a mechanism for registering ULA-central prefixes & PI. For those who don't recall, the reason ULA-central was tabled was that it was seen as a potential end-run to acquire PI space in the absence of appropriate policy to do so out of a range recognized for global routing.
The need for keeping some things local while others are global is real, and the lack of appropriate mechanisms to accomplish that through the routing system that is designed to deal with path selection leads to entire industries for fragile work-arounds along with their increased complexity.

i think that this article will help inform the debate around the ipv6 transition:
