Hi,
We have a domain that used to be a flat network (172.17.2.0 /24), but was recently changed to include other subnets too, including 172.17.3.0/23 and 172.17.5.0/24.

I created a single reverse DNS zone called:
0.17.172.in-addr.arpa
But when i try to go to a forward DNS Host (A) record and update its PTR (for a host that's now on the 172.17.3.0/24 subnet), i get the error: "Warning: The associated PTR record cannot be created, probably because the referenced reverse lookup zone cannot be found".

What am I doin wrong?
