Name server to domain name lookup?


Hello HN, DNS related question here. It's easy enough to find the name servers associated with a particular domain via whois, et cetera. What about the other way around?

For example, my domain and website uses ns1.dreamhost.com (and ns2 and ns3) for name service.

Is there a way to find out what other domain names use those servers (or any one of them?)

Thank you.

Probably not what you were looking for. People do collect and correlate WHOIS db's too.

Zone files are available for lots of TLDs, once you've got the data you can analyse it:
