## what is WHOIS?
|

|

WHOIS is a network protocol used to query a database that contains information about domain name registrations and IP address assignments. The WHOIS database is maintained by various organizations, including Internet Service Providers (ISPs), domain name registrars, and regional Internet registries.

The most common use of WHOIS is to obtain information about a particular domain name or IP address. To use WHOIS, simply enter the domain name or IP address in a WHOIS lookup tool, which will query the appropriate WHOIS server and return the relevant information.
