Each active domain name is registered on the name of a person and through the registration procedure many details are introduced - the owner’s names, address, email, mobile phone number, and so forth. These details plus the registrar company name and the registration/expiration dates is recognized as WHOIS of the domain address and in accordance with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it ought to be current and correct. If a domain name has invalid WHOIS details, it may be reported and if the details are not fixed, the Internet domain can be erased or the registrar company could take over its ownership. By default, the WHOIS information 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 businesses. All businesses that offer registration services are obliged to provide a simple way for their clients to access and edit the WHOIS details of any domain name they own as much as the specific TLD allows it.
