The so-called WHOIS details of any registered domain name contain info about the registrar company, the registration and expiration dates, as well as the names, telephone 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 get all this information through a command line or by using one of the many Internet websites which provide WHOIS lookup services. All details ought to be up-to-date in accordance with the policies of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the info is not correct, the domain name can be reported and the result might be its removal or losing its ownership. A few country-specific domain address extensions have specific limitations regarding the modification of their WHOIS info, but in the typical scenario any detail can be changed easily and at any moment. Such an adjustment will appear on lookup websites within twenty four hours.
