Whois is an Internet database that contains information on domain names, including the name
servers associated with the domain name, the domain registrar, registrant and the domain's
Administrative and Technical contacts. By performing a WHOIS search, you can find out when
and by whom a domain was registered, their contact information, where the website is hosted,
when the domain expires, and more.
The Whois is also a tool that searches the domain name information contained in WHOIS databases.
It is generally used to check the availability or ownership of a domain name.
