Hi, Can NSLOOKUP list all DNS domains pointing to a specific IP? I am trying to do what the following service does by using NSLOOKUP: http://www.yougetsignal.com/tools/web-sites-on-web-server/ Thank you,

Not really, unless say, the owner of the reverse lookup zone for that IP added every hostname as a PTR record, but that doesn't really happen. JoeJoseph M. Durnal MCITP: Enterprise Messaging Administrator

Thanks Joe, Do you know how the site I mentioned gathered their data?
