Each active domain is registered on the name of a person and throughout the registration process many details are submitted - the owner’s names, address, e-mail, mobile phone number, and so on. These details combined with the registrar company name and the registration/expiration dates is referred to as WHOIS of the domain address and in compliance with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it ought to be current and accurate. If a domain has wrong WHOIS details, it could be reported and if the details aren't fixed, the domain could be deleted or the registrar company could take over its ownership. By default, the WHOIS info is public and can be seen on numerous lookup sites, or for a smaller number of country-code extensions - on the sites of the respective Registry companies. All companies which offer registration services are obligated to provide a simple way for their clients to access and modify the WHOIS info of any Internet domain they own as much as the particular TLD allows it.
