Well, the same way you would move a /128 around I guess.

None, apart from that a host seldom has a single /128 but instead several 
/128:s. The biggest upside is that you don't need to do DAD handling 
between participating wifi routers (since the host is alone in the /64, 
there is no need to do inter-router DAD).
