whois

An Internet directory service for looking up names of peopleon a remote server. Many servers respond to TCP queries onport 43, in a manner roughly analogous to the DDN NICwhois service described in RFC 954. Other sites providethis directory service via the finger protocol or acceptqueries by electronic mail for directory information. OnUnix the client command is

whois -h server_name person_name

You can also type "telnet server_name 43" and then type theperson's name on a separate line. For a list of whoisservers, FTP/Gopher: sipb.mit.edu. Or

whois -h sipb.mit.edu whois-servers

As the above command demonstrates, whois can find informationabout things other than users, e.g. domains, networks andhosts.

See also finger, X.500, white pages.

Whois

Before the Web, Whois was strictly an Internet service used to query a host and find out if a certain user was registered on that system. Originally developed by the military, others followed with their own Whois databases, which provide white pages directories. See finger.

Directory of Domain Names
Whois databases have become the master directories for domain name registrations. When a new domain is added or changed, the information is sent to the appropriate Whois database. Domain name registrars may provide a search function on their sites that can access various or all of the Whois databases. Following are examples of websites that provide information from the Whois databases:

WHO-IS SITES www.WhoIs.sc www.BetterWhoIs.com www.InternNIC.net www.uWhoIs.com www.EasyWhoIs.com www.FreeWho.com (tracks Whois sites) www.TekTips.us (tracks Whois sites)
