The so-called WHOIS details of every single registered domain name include information regarding the registrar firm, the registration and expiration dates, in addition to the names, contact number, postal address and e-mail address of the owner, the administrator and the tech/billing person. WHOIS is a special protocol that allows you to get all of this info through a command line or by using one of the numerous Internet websites that offer WHOIS lookup services. All information should 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 accurate, the domain name can be reported and the result might be its deletion or losing its ownership. Some country-specific internet domain extensions have certain limitations in connection with the modification of their WHOIS details, but in the standard situation any detail can be edited openly and at any time. Such a change will show up on lookup websites within 24 hours.
