What is WHOIS

WHOIS is a query and response protocol that is widely used for querying databases that store the registered users or assignees of an Internet resource, such as a domain name, an IP address block, or an autonomous system.

When you register a domain name, the Internet Corporation for Assigned Names and Numbers (ICANN) requires your domain name registrar to submit your 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.
