Thomas,
I would like to see this draft revived, as it seems to be more or less what
we were looking for with 2006-2. Stewardship to guarantee uniqueness, and
delegation in ip6.arpa.
I think the draft will need some revision to make it more palatable, but
will reserve my comments for IETF mailing list.
Greg

Question:
I gather that resurrecting
http://tools.ietf.org/html?draft=draft-ietf-ipv6-ula-central
would also solve the technical problem at hand (since the technical
requirement seems to be globally-unique address space, with no need/desire
to have it be globally routable).
I understand that RFC 4193 style addresses are not "unique enough" for that
purpose.
Would there be interest in resurrecting the ula-central document?
Pros:
1) globally-unique space would be available to everyone, including end
sites. I.e., for pretty much any purpose. Even during the ARIN
meeting, it was pointed out that anyone with an ASN could/would
presumably want something like this.
Cons:
1) ARIN pretty vocally shot down the document a year or more ago, and
the IETF basically decided "we don't need this so badly as to have
a showdown with the ARIN community". Having said that, I (and
others) still think the idea has some merit and would be willing to
push on it on the IETF end, assuming we wouldn't get a repeat
reaction at future meetings for our efforts...
Note: AFAIK, no such reaction seemed to come out of APNIC or RIPE.
2) Does solve Jason's problem, but perhaps there is no desire to fight
the larger battle at the expense of just solving the narrow/simple
problem (i.e., just for ISPs). Note, however, that it will
presumably take at least another 6 months (until the St. Louis
meeting) to make progress on this. (Realistically, it would
probably also take 6 months to get the ula-central document through
the IETF, assuming there was no significant opposition from ARIN,
so I'm not sure either approach is necessarily longer).
3) Would make such address space available to everyone, including all
end sites, not just ISPs. Not sure this is necessarily bad, but it
will result in orders of magnitude more such addresses in use. And
the concerns raised in the past centered around the fear that ISPs
would be asked/forced to route them...
I know that there is at least one person willing to resurrect the
ula-central document, but I (personally) don't want to invest cycles in it
if it's going to get a frosty reception in ARIN again. Been there, done
that.
Thomas
