The so-called WHOIS details of every single registered domain contain info about the registrar organization, the registration and expiration dates, along with the names, telephone 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 retrieve this info either through a command line or using one of the numerous websites that provide WHOIS lookup services. All information should be up-to-date as per the regulations of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the details are not legitimate, the domain name can be reported and the result may be its deletion or losing its ownership. A few country-specific internet domain extensions have certain limitations regarding the modification of their WHOIS details, but in the general situation any detail can be edited openly and at any time. Such an adjustment will show up on lookup websites within 24 hours.
