every other attempt to add rapid renumbering and transparent multihoming 
has been rejected. NAT, by not trying to do those things and by not 
saying it would do those things, snuck under the defenses.

no multi-national enterprise should give real external addresses to all 
of its internal endpoints, for at least three reasons:

1. the internal structure should not be visible or guessable.

2. reachability should be prevented by more than just firewalls.

3. you can add and drop transit providers as often as you want.

NAT did that. nothing else could have or did.
