The so-called WHOIS details of any registered domain include info about the registrar organization, the registration and expiration dates, plus the names, contact number, postal address and email address of the owner, the admin and the tech/billing person. WHOIS is a special protocol that allows you to get all this information either through a command line or by using one of the numerous websites that offer WHOIS lookup services. All info must be up-to-date in accordance with the policies of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the information is not correct, the internet domain can be reported and the result may be its deletion or losing its ownership. Several country-specific internet domain extensions have specific limitations for the change of their WHOIS information, but in the typical scenario any detail can be changed openly and at any moment. Such an adjustment will appear on lookup sites within a day.
