Discover Unreferenced Zones/Records

[Sten Carlsen]

There might be some zones that are rarely used, you may see those as
dead using that method.

I was thinking of a script that would take your list of zones
(essentially the .conf file) and for each zone do something like a "dig
+trace" and look for whether your servers are listed as name servers for
that zone.

Those you are no longer listed in can be removed immediately, those
where you are listed but has no or very little traffic, you can make
inquiries about and act accordiingly.

Just my 0.02EUR
