It is indeed recommended for the freeipa server to have a fixed IP
address with proper A/AAAA and PTR records set.

Yes, if you use the --setup-dns switch the install script will set up a
DNs server for you. There you can mamage both direct and reverse zones
if you wish. All you need to do is to make sure forwarders redirect to
the amazon provided DNSs so you can resolve other domain names and then
point all your clients at your own DNS server on the freeipa server.

This should make it easier to handle the requirements.

Simo.
