IP numbers are not portable, DNS names are. You can move toad.com anywhere on the network, but you can't move 140.174.2.1 anywhere on the network.
FYI - IP portability, both in the sense of disconnecting in one place and reconnecting in another and in the sense of keeping a TCP connection alive while moving from place to place are design goals of IPv6
But IPv6 also brings link-level encryption and makes subliminal communications channels trivial; Big Brother (now does anyone know what that that translates to in Chinese?) won't stand for that... The enhancements of IPv6 make a lot more possiblities for secure channels and untracable packet-level communications available. Instead of needing to jump through many hoops you just have to subvert one of the new goodies IPv6 gives you for free :) jim
