IPv6 has made it possible to renumber the network almost automatically.
it seems possible to make that change without a "flag day" and an outage.
however, the tools are mostly *NOT* there for similarly easy renumbering
of router ACLs and firewall configs and DNS, so as the size of the network
increases, large organizations are saying there is still a significant
cost to renumbering (at this time...).  one can only hope that appropriate
tools will be developed to make full renumbering reasonably painless.

or the appropriate protocol enhancements are made so that local numbers
become much less relevant to global routing?			/Lea
