IMHO, there is a need for both tools and guidance, and perhaps also
for minor protocol tweaks.  this was true even with A6 records.

if someone were to write a "how to renumber your network" document,
with appropriate consideration for all of the components of the 
network that might need to be tweaked (incl. routers, firewalls,
software that is configured to allow access only from local IP
addresses) and also consideration for what it takes to keep software
from breaking during the switch-over (listing different phases 
and recommending times for each) the exercise of writing this document
might also serve to identify any missing bits of protocol and missing
tools. perhaps I've missed it, but I don't think I've ever seen 
anything like a complete story on how to renumber a large network -
and until we have that, how can we be sure that the necessary pieces 
are all in place?
