What would it give to you?
AD DC uses FQDN to decide which KDC is responsible to issue TGT (and
other tickets). If it belongs to its own DNS domain, no attempt to issue
cross-realm TGT will be done and Windows users will never get tickets to
services running on these IPA machines.
You would really need to address IPA machines by their host names in
ipa.zone.corp domain and never by .zone.corp. At this point there is no
need to keep them in .zone.corp.
Good point. May be that CNAMEs from old name to the new name (in IPA sub-tree)
could solve your problem. Kerberos usually follows chain of CNAMEs so it

The key here is that for IPA and AD to be able to work together in a trust,
they need to be in separate domains with realm matching this domains. In
case, it seems to me that a following scenario would work the best:
* AD with domain zone.corp and realm ZONE.CORP
* IPA with domain ipa.zone.corp and realm IPA.ZONE.CORP
Ideally, IPA should have DNS installed and have the ipa.zone.corp delegated
from the AD DNS (or other DNS you use).
