IPV6 renumbering painless?

I guess you also want to announce a /64 into the IPv6 BGP tables ?

Correct me if I'm wrong, but doesn't IPv6 do away with the need to renumber when switching providers? So if RFC 2462 is right, and you use DNS outside your network and you update that DNS at the moment of switching providers, everything on your network automatically acquires new IPv6 globally routable addresses as soon as the gateway router is connected to the new provider. Seems to me that with a little bit of help from a "Change providers" tool, this would be virtually painless without the need to own or announce a small globally unique prefix. --Michael Dillon
