Each active domain name is registered on the name of a particular person and throughout the registration procedure many details are presented - the owner’s names, address, email, telephone number, and so on. This info as well as the registrar company name and the registration/expiration dates is recognized as WHOIS of the Internet domain 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 corrected, the domain address may be erased or the registrar company may take over its ownership. By default, the WHOIS information is public and could be seen on a lot of lookup sites, or for a small number of country-code extensions - on the Internet sites of the respective Registry businesses. All businesses that provide registration services are required to provide an effective way for their clients to access and modify the WHOIS info of any domain name they own as much as the specific TLD allows it.
