The so-called WHOIS details of every single registered domain include information regarding the registrar organization, the registration and expiration dates, in addition to the names, phone 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 obtain all this info through a command line or by using one of the many Internet websites that offer WHOIS lookup services. All details should be up-to-date as per the policies of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the info is 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 concerning the editing of their WHOIS information, but in the typical case any detail can be changed openly and at any moment. Such an adjustment will show up on lookup websites within a day.
