One factor to keep in mind is DNS, both for hosts and for IP
addresses.
If you have servers that you want visible form the outside world, then
you need to have DNS RR records for them. If you have e-mail clients
that you want the outside world to accept mail from, then you need to
have FCrDNS. If you are using return addresses in e-mail that you want
the outside world to consider valid, then you must have an MX record
for the mail domain and an A record for the actual host. So in the
general case dynamic IP addresses require dynamic DNS for both hosts
and IP addresses.
