Find all authoritative domains for a nameserver?

[Edward DeLargy]

So,
     Had this same issue where a customer forgot whom they actually
supported. Grep the named.conf for the zones (Shows active Zones). Then
grep the db file for the A records of each active zone. Then write a script
to querry 8.8.8.8 or whois for the names. This returns the customer info.
You can also set up query greps for dns logs. Anything answering is where
you would look then again write a script against whois on the internet.No
easy way around getting customer info other than a script against whois if
you have a ton of A record returns.

Hope this helped,
Ed
