large ipv4 deployments want an
absolutely minimal, compatible, feature-match upgrade to ipv6.
I'm not in the loop, but it seems to me that this is obvious.
What has the IETF done to define a way that IPv4 deployments
can make the transition they want? If IPv6 is better than IPv4 in
every way, this goal must be attainable.
