Whois
This program is FREEWARE.
DiamondCS Whois is a utility to retrieve information about registered domains, including information such as ownership and business information, when the domain was registered, and sometimes even addresses, phone numbers, and so on.
This utility includes automatic server selection by default, optional custom server selection, and automatic Whois server redirection, so all you need to do is give it the domain name you want information about, and let it do the rest!
