You could use nslookup or you could use dig as well probably.  These will
let you interogate the nameserver database to help you to find information
about the sites.

assuming you have the site 1.2.3 which you wish to know, you could find out
the machines in the domain and their names by doing the following

nslookup	(run nslookup)
root		(set server to the root name server)
ls 3.2.1.in-addr.arpa.	(list the machines in this domain and name servers
                         for the same)

This method isn't foolproof as many machines have no reverse name lookup
information.  Also, the root name server may not have any information on
this domain and you will have to find one that does.

I haven't used dig much, but I think it will do similar things.

NOTE:  All these programs will get you is the name of the machine and some
idea of who is above them.  You could probably achieve the same with a
small program that calls gethostbyaddr.  They will not give you info on the
organisation behind the machine, but you can often hazard a guess.  Another
way to find the machine name is to telnet to port 25 and then type quit.
Sendmail lists the full machine name as part of the version string it
prints when you connect (usually)
