Combine PTR zones

[Todd]

I currently have a primary win2k3 DNS zone with all my
PTR zones broken out by class C IP's (all non-routable
ranges). I'd like to eliminate headaches with new subnets
on the network by just switching to a Class A non-
routable PTR zone (10.in-addr.arpa). Will DDNS clients
register themselves in both the new 10.0.0.0 PTR zone and
their current 10.x.x.0 PTR zone? Can I move all the
records to the new zone. I have something like 45 Class C
PTR zones currently.

I currently have a primary win2k3 DNS zone with all my
PTR zones broken out by class C IP's (all non-routable
ranges).

Just for reference: they are "locally administered" and routable,
just not routable on (the backbone of) THE Internet.

I'd like to eliminate headaches with new subnets
on the network by just switching to a Class A non-
routable PTR zone (10.in-addr.arpa). Will DDNS clients
register themselves in both the new 10.0.0.0 PTR zone and
their current 10.x.x.0 PTR zone?

If they have 10-net addresses and you set it up correctly (e.g.,
dynamic Reverse zone etc.)

Can I move all the
records to the new zone.

Not easily and not worth the trouble probably.

I have something like 45 Class C
PTR zones currently.

You could just create a single reverse zone for ALL
class-C addresses: 168.192.in-addr.arpa

When re-registered they would all be together -- or
you could leave the current mess and all new ones
in undefined zones would register in the "larger" zone.
