> I have a problem that I'm hoping that you can help with. I have a Parent
> and a Child zone that are obviously authoritative for different forward
> zones, but share IP address space (e.g. systems in both the parent and
> child zones could have a 10.20.4.x address). In my configuration the
> servers with the child zones forward to the parent servers for zones
> they are not authoritative for.
> 
> My problem is that this arrangement is causing me some problems in
> providing complete reverse zone mappings - i.e. both the parent and
> child servers may both be authoritative for 4.20.10.IN-ADDR.arpa, and
> since only approx. 1/2 the addresses may exist in any one server,
> depending on which server is queried, only 1/2 the addresses are
> available for reverse lookups. In looking for a solution, I'm wondering
> if it's possible that using the "forward first" option on the zone
> statements may provide a workaround. Any ideas?
> 
> Many thanks in advance.
