Something I've noticed is that it's creating PTR records.

Yes, they are a requirement for FQDNs and for Mac OS X.

Which does not mean they have to be created on the same server.

It shouldn't be,

Yes it should.

No. If you don't own the IP address range - like, say, the OP - you're not authoritative for the reverse lookups, and therefore not supposed to create the PTR records. Of course one should make sure the records exist (i.e. have the owner of the address range create them), but that's a different story.

That's right, Ansgar; the server is colocated, and we're not responsible, so my understanding is that we shouldn't have those PTRs...

Is that true, Dan, or am I still being wooly?

No you MUST have PTRs and they MUST match.

The question is not whether PTR records are required, but who must provide them. And I sure hope it's sufficient for OS X when the server authoritative for the address range provides them, because everything else would be utterly braindead.

 How you do this is an implementation detail and a matter of separate
 discussion.

Nope, it's the exact subject of *this* discussion, because ...

And YES you can do this.

... the OP was asking HOW to deal with automatically created PTR records WITHOUT having to stop using Server Admin.

And there's no disconnect here.

If you don't own these IP addresses then you need split horizons. Period. So use your OS X Server and SA and to serve DNS for your horizon.

Moreover if you dont' own your IP addresses then you shouldn't be host DNS for public consumption either so there's no problem here.
