Each active domain is registered on the name of a particular person and during the registration procedure many details are introduced - the owner’s names, address, email, mobile phone number, and so forth. This info combined with the registrar company name and the registration/expiration dates is known as WHOIS of the domain and in compliance with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it has to be current and correct. If a domain name has wrong WHOIS details, it can be reported and if the details are not corrected, the Internet domain can be deleted or the registrar company may take over its ownership. By default, the WHOIS information is public and could be seen on numerous lookup Internet sites, or for a limited number of country-code extensions - on the sites of the respective Registry organizations. All companies that offer registration services are required to provide an uncomplicated way for their clients to access and modify the WHOIS info of any domain they own as much as the particular TLD allows it.
