When you register a domain name (for example, example.com or example.com.ru), the Internet Corporation for Assigned Names and Numbers (ICANN) requires your domain name registrar to submit your personal contact information to the Whois database. Once your listing appears in this online directory, it is publicly available to anyone who chooses to check domain names using the Whois search tool (for example www.whois.ru). You can perform a Whois search using Google: just search for [ whois example.com ] or [ www.example.com.ru whois ].
Whois (pronounced as the phrase who is) is a query/response protocol that is widely used for querying databases in order to determine the registrant or assignee of Internet resources, such as a domain name, an IP address block, or an autonomous system number. For example, www.example.com.ru translates to 188.8.131.52. Another example, www.example.com translates to 184.108.40.206. Domain example.com resolve to a server managed by ICANN. Whois lookups were traditionally performed with a command line interface application, but now many alternative web-based tools exist. For example http://www.whois.ru, http://www.whois.com, http://www.whois.com.ru. Whois services are typically communicated using the Transmission Control Protocol. Servers listen to requests on the well-known port number 43.
The Whois system originated as a method for system administrators to obtain contact information for IP address assignments or domain name administrators. The use of the data in the Whois system has evolved into a variety of uses, including:
