I covered that. Edge routers transition 1.x.x.x.x to x.x.x.x as a default, and x.x.x.x to 1.x.x.x.x. This is an interim change, so that ipv4 can communicate to ipv4 forever. Legacy systems can be supported on ipv4 only, relegating them (just as they are now!) to not having access to that new address space.

You realise that this idea of "embedding a smaller, old address space inside a newer bigger one" has existed in IPv6 for a pretty long time now?
