The so-called WHOIS details of any registered domain name include details about the registrar firm, the registration and expiration dates, along with the names, phone number, postal address and e-mail address of the owner, the administrator and the tech/billing person. WHOIS is a special protocol that enables you to retrieve all of this information through a command line or via one of the numerous sites which provide WHOIS lookup services. All info should be up-to-date as per the rules of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the details are not correct, the domain could be reported and the result could be its removal or losing its ownership. A number of country-specific domain extensions have certain limitations for the change of their WHOIS information, but in the standard scenario any detail can be edited easily and at any time. Such a modification will appear on lookup websites within 1 day.
