Re: NATs *ARE* evil!

[Keith Moore]

the fact that IPv* doesn't distinguish between who and where does 
cause some problems, but does not significantly impact the ability 
to route IPv* packets.  even if you free IP addresses from any kind
of role as host identity (which IMHO would be a good thing except that
nobody has produced a satisfactory solution to the problem of mapping 
between the two), IP addresses will still need to be fairly stable,
and  there will still be a nontrivial amount of effort associated
with renumbering as the network topology changes.
