Question for DNS pros

[Paul Schmehl <pauls () utdallas edu>]

Can this be done?

Conditions:
1) You know an IP address that is running a DNS server.  (IOW, it responds 
to digs.)
2) You do not know the hostname or domain of the host.
3) The DNS server does not allow zone transfers.

You want to find out *all* the domains that that DNS server is 
authoritative for.  (Essentially you're trying to find out what's in the 
named.conf file rather than zone file info.)

Has anyone written a tool that can do this?  I thought about the 
possibility of parsing all the registration sites for the Primary and 
Backup NS, but that would take forever.  I imagine you could write a perl 
script that would access the web interfaces, do the queries and return the 
results, but it would run for days...
