- 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)
