Whois: Whois Tool
built 634 days ago
WHOIS is a DNS tool that identifies who has registered a particular domain name. WHOIS works by querying the WHOIS database with a domain name, and receiving back detailed information including contact information for the registrant, contact information for the host, technical information such as relevant IP number addresses, and expiration dates of the domain name. WHOIS is a tremendously useful tool... WHOIS data is openly available to everyone everywhere - a privacy issue, and a significant portion of WHOIS data is either falsified or is incomplete.

Lack of WHOIS server lists: There is no central list of WHOIS servers. Therefore, people writing WHOIS tools need to find their own list of WHOIS servers, and different WHOIS tools may contact different WHOIS servers.
