Every active domain name is registered on the name of a person and throughout the registration procedure a number of details are introduced - the owner’s names, address, email, telephone number, and so on. These details in addition to the registrar company name and the registration/expiration dates is known as WHOIS of the domain address and in agreement with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it should be current and correct. If an Internet domain has invalid WHOIS details, it may be reported and if the details aren't fixed, the domain address can be erased or the registrar company may take over its ownership. By default, the WHOIS information is public and may be seen on numerous lookup Internet sites, or for a small number of country-code extensions - on the websites of the respective Registry companies. All businesses that provide registration services are obligated to provide an effective way for their clients to access and edit the WHOIS info of any domain they own as much as the particular TLD allows it.
