I just retired a BM server and had to move my external DNS zones from
it to
the same server as my internal DNS zones.

Then to my consternation I could not figure out how to tell the NW
that certain zones should not be publically exported.

So, I moved my public ones to another NW server and now only the
public zones are being transferred out rather than all of them.

Is there not a way to do this? I noticed that the DNS/DHCP console
that all the IPs in each server where probably being used for DNS
another thing that should be configurable.
