by on October 26, 2009 · 1 comment· LAST UPDATED October 26, 2010


How do I find out who owns a Internet domain name and its ip address?

The WHOIS system is used by domains and ip address on the Internet. It is used by system administrators to obtain contact information for IP address assignments or domain name administrators. Use whois command as follows:
$ whois domain-name
$ whois -h
$ whois

Sample outputs:

        Dns Admin
        Google Inc.
