I currently have two separate AD forests that exist within the same subnet. The two forests have independent copies of the reverse lookup zone for that subnet.

Example:

Domain A DC1: 10.1.1.1/24

Domain A DC2: 10.1.1.2/24

Domain A AppServer1:10.1.1.3/24

Domain B DC1: 10.1.1.11/24

Domain B DC2: 10.1.1.12/24

Domain B Appserver1:10.1.1.13/24

What I'm after, is a configuration that allows this reverse zone to be shared between them so that both sets of DNS servers can make updates to the zone.

This kind of thing is a little far from my everday work, so a kick in the right direction is a welcome suggestion as well. Decoupling one AD into new segments is a possibility I'm open to but would like to avoid if possible. If there is a DNS related solution I'd prefer that.
