merging reverse zone data obtained from two different masters

Ideally, whatever frontend you use to maintain the "forward" records for these zones, should be smart enough to, in parallel, populate the corresponding entries in the common reverse zone.

But, failing that, it shouldn't be that hard to write a script that periodically pulls zone transfers of the forward zones and merges that data to create/update the common reverse zone. If the ranges used by these Zone1/Zone2 hosts overlap, you'll have to decide how to handle collisions, of course.

Subject: merging reverse zone data obtained from two different masters

We have hosts in two different zones but use same subnet. Zone1 is generated by Master1 and Zone2 is generated by Master2.

Slave1 runs BIND and would like to merge the reverses generated on Master1 and Master2. How do I do this?
