I wouldn't be suprised if in a few years some EU/US law mandates IP number
portability, just like people have with their cellphones. Imagine what
that will do to the routing tables. How many /32s can we get into the
RIBs these days?
The next obvious step would be complete street address portability, for
all kinds of usage, like telling the cab driver where to go to get you
home. Once you have lived on 1234 Main Street, it should be yours!
