I'm not sure I understand this. For most of the application layer
protocols that I deal with everyday (SMTP, POP, IMAP, HTTP) , and a
large class of similar protocols, a stable DNS name is perfectly
reasonable substitute for a stable IP address. Do you think that
there is not a huge class of protocols that can reasonably use
dynamic DNS, or do you simply think that there are a significant
number of problems for which a stable IP address is required?
...or that there's no need for platforms to support mobile IP.
Now, there is no question that anyone who thinks it's reasonable to
change an IP address when there exists an active connection to that
IP address is just being loopy. This is an issue for mobile IP
(leaving aside whether the current crop of mobile IP protocols is a
good solution for that problem), but I don't see that as the problem
that dynamic DNS is trying to solve.
