The so-called WHOIS details of every registered domain contain information about the registrar firm, the registration and expiration dates, along with the names, phone number, postal address and e-mail address of the owner, the administrator and the tech/billing person. WHOIS is a special protocol that permits you to obtain this info either through a command line or using one of the numerous Internet websites that provide WHOIS lookup services. All info must be up-to-date in accordance with the rules 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 removal or losing its ownership. Several country-specific internet domain extensions have certain limitations for the change of their WHOIS info, but in the general case any detail can be changed openly and at any moment. Such a modification will appear on lookup sites within 1 day.
