We do not enable the DNS on replicas by default, it is an admin choice
on which replicas they want to enable the DNS service.

When you install the replica you can pass the --setup-dns flag.

If you forgot to do so or if you later change idea and want to install
the DNS piece you can simply run ipa-dns-install on the replica you want
to have another DNS available.

That depends on your network topology.
At the moment we do create a reverse zone for you by default, but you
can use it, disable it, or just remove it if you have reverse lookups
handled elsewhere.

In future though we plan to improve the DNS plugin so that it will
automatically update also the reverse zone (if managed by IPA) on
clients dynamic DNS updates.

It is not necessary, although I would recommend that you properly set
the ptr records at least for your servers in the DNS that is managing
your reverse zones.
