IPA just needs a sane, available DNS server. It doesn't need to own it.
There are some advantages to IPA owning the DNS server but as long as
you're willing to maintain the records that IPA needs you'll be fine.
If you plan to ever, maybe, even an outside chance want to integrate
with an AD server via trust you'll want to pick a unique realm for IPA
and a separate DNS zone (ipa.corp.example.com). Even without AD doing
that it can still be a good idea.
