I don't know how practical it would be to to try and monitor the dns
server queries to help id which entries are used vs unused. But it
might be something to consider sooner than later as you'd want to let
this run for quite some time to build some statistics.
Just throwing the idea out there.
As for figuring out what is unused or not, there
isn't any good way of
determining that.
