Once NAT66 gets out, I can imagine even more damaging headlines
(which conveniently miss all the subtleties of the message in
section 3 of http://www.ietf.org/internet-drafts/draft-mrw-behave-nat66-00.txt)
: "IETF Standardizes IPv6-to-IPv6 NAT".
Well, if that's what we want to avoid, we shouldn't be coy and come
out and say that IPv6 NAT won't be accommodated in IETF protocols.
What seems to be happening today is that we all look the other way and
pretend the issue doesn't exist, because we either assume that of
course there won't be any IPv6 NAT or of course there will. So we are
on our way ending up with the same situation that we encountered with
IPv4: suddenly, it's no longer realistically possible to deploy a
protocol that isn't NAT-friendly, but there are so many different NATs
that it's impossible to be friendly to them all, and many of them
operate is very suboptimal ways that could have been avoided with some
