The so-called WHOIS details of any registered domain contain information regarding the registrar organization, the registration and expiration dates, in addition to the names, contact number, postal address and e-mail address of the owner, the administrator and the tech/billing person. WHOIS is a special protocol that lets you retrieve all this info through a command line or using one of the numerous sites that offer WHOIS lookup services. All information ought to be up-to-date in line with the policies of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the details are not legitimate, the domain may be reported and the result could be its removal or losing its ownership. A few country-specific domain extensions have specific limitations in connection with the modification of their WHOIS info, but in the standard situation any detail can be edited openly and at any time. Such a change will show up on lookup websites within twenty four hours.
