Problem with Net::DNS is that it is looking over the Internet at a functioning DNS server. I'm looking at tools to parse the raw BIND zone files and look for errors that would prevent a server from starting.

Further, certain entries are perfectly allowed on a working server, but can indicate an oversight. A record like this:

@        IN        MX        10        mail.example.com
[download]

This is a MX record pointing to mail.example.com.example.com. Perfectly legit to an external source, but not really pointing where the author wanted. That's the kind of thing I'd like to generate a warning on, on the admin side of things.

I suspect what I'm asking for is a very large library of REs that might have something useful in terms of DNS.
