The so-called WHOIS details of every registered domain name contain information regarding the registrar organization, the registration and expiration dates, plus the names, telephone number, postal address and e-mail address of the owner, the admin and the tech/billing person. WHOIS is a special protocol that permits you to retrieve all of this information either through a command line or through one of the many websites that provide WHOIS lookup services. All details ought to be up-to-date in accordance with the rules of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the information is not legitimate, the domain name could be reported and the result may be its removal or losing its ownership. Some country-specific domain address extensions have specific limitations concerning the editing of their WHOIS details, but in the general situation any detail can be modified freely and at any time. Such a modification will appear on lookup websites within 1 day.
