Izumi and all, I am afraid Randy is 100% correct. After years of working in IPv6 myself and in general address allocation issues from time to tame for many years, Randy has clearly demonstrated through much empirical evidence to be correct in his assertions. That said however, the problem with IPv6 is in part the protocol and it's implementation aspects itself, and part the concerns of over allocation to some LIR's and RIR's, which has proven to be true with IPv4 and goes back even prior to 1996. Now there is discussion about a "Black Market" for IP addresses which is very troublesome. Again though much of this developing problem is based in disagreement between RIR's and the IANA. Why is that not a surprise? Izumi AIZU wrote:

FYI. I hope what Randy reveals is not 100% true, but it maybe so very much. See his presentation, URL below.

Izumi and others may find this paper interesting in respect of IPv6/IPv4 interoperability.

http://www.nanog.org/mtg-0710/presentations/Bush-v6-op-reality.pdf

It's from Randy Bush, very much an IETF stalwart and true believer. Randy Bush has compared the IPv6 rollout (starting from 1995) with the war in Iraq - "no transition plan, declared victory before the hard part started, no real long term plan, no realistic estimation of costs, no support for the folk on the front lines [and continual declaration that] victory will be next month" –

To which comparison I would add acute embarrassment at the failure, which leads to denial and coverups and all sorts of attempts to wish the problem will go away.
