Sadly, nothing now. It would be whatever was standard in a FC 27 install. I had to abandon FreeIPA due to time constraints and I moved back to stock Bind9. System Admin work is one of those "extra" task I have and not my primary job. I simply ran out of time; 4 days of lost productivity has my management a bit unhappy. Sorry I didn't save the VM.
I did find one other quirk of using FreeIPA vs stock Bind9. Seems that FreeIPA will allow you to create a hostname with an underscore. Bind9 complained bitterly about that. It'd have been nice if FreeIPA would have warned or prohibited me from adding the underscore in the first place. Granted it may be that Bind9 is being too restrictive.
"check-names ignore;" in the named.conf would have enabled you to deal with underscores in hostnames in Bind9.
