The so-called WHOIS details of every single registered domain name include details about the registrar firm, the registration and expiration dates, and also the names, contact number, postal address and e-mail address of the owner, the admin and the tech/billing person. WHOIS is a specific protocol that enables you to retrieve all this information through a command line or via one of the numerous sites that offer WHOIS lookup services. All info must be up-to-date in line with the policies of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the info is not accurate, the domain name may be reported and the result may be its deletion or losing its ownership. Some country-specific domain address extensions have certain limitations in connection with the editing of their WHOIS information, but in the standard situation any detail can be changed openly and at any moment. Such an adjustment will appear on lookup Internet sites within twenty four hours.
