Yes and no.
I agree that ARIN doesn't need to make policy with regard to ULA.
do think that the situation above makes it pretty clear that we
a good universal PI policy going forward, or, the IPv6 swamp will,
be built out of ULA and randomly distributed /48s and /64s.
Organizations need portable addressing. Eventually, the internet is
have to simply solve the scaling problems associated with the current
interdomain routing paradigm. I believe this will require a paradigm
most likely involving some form of ID/Locator split.
I propose a relatively light-weight and backwards compatible mechanism
I welcome comments on it.
However, my fear is that as long as the IETF and router vendors believe
they can get away with extending the current paradigm, efforts to truly
resolve this issue will be delayed until it approaches a crisis. At
point, it will probably be too late to take graceful action in time.
