I'm quite aware of the IETF transition strategy.
20+ years in isn't apparent that it is working. The IETF cannot disable
IPv4 from it's properties in the forseeable future. It is equally
unforseeable when a client can communicate only IPv6 end to end.
The sorry reality is that the centralized network combined with the fact
that a single IPv4 address is sufficient for a small country (with a
port overloading NAT) there is no urgency to the transition.
I would love to be proven wrong of course...
