DNS server

Post by hasirani » 22 Mar 2011, 05:14

How do I get a list of sites registered with a DNS Name Server? I am trying to get some information from a specific dns server. Specifically, I need a list of the ip addresses for sites registered with that dns server. Also, a way to programatically access that information would be nice, as I am working on a program in Java that will be using the information.

you want to ask a remote server what IP addresses it is giving out? That would be one hell of a security breach!
If not: please specify in shorter sentences what you want.

Yes, plus you are looking for reverse lookups, which isn't part of how DNS works.

that last sentence I do not agree with. DNS servers do in fact dole out IP addresses when supplied with a domain name. Now I suppose you can hack it into giving up IXFR records which contains all ip addresses for a domain, but you cannot ask it which domains it is holding data for, as the recursive nature of DNS will then offload the entire worlds DNS structure on you.

Actually, what does all this have to do with Bubba? More a question for the BIND user list.

Ubi is right, of course.
But if you have your own lowly domain registered, you will know that reverse lookups only works for some, so the results for such a query would always be inconclusive.
