The so-called WHOIS details of every single registered domain contain information regarding the registrar organization, the registration and expiration dates, in addition to the names, contact number, postal address and email address of the owner, the administrator and the tech/billing person. WHOIS is a specific protocol that enables you to obtain this info either through a command line or by using one of the numerous Internet websites that offer WHOIS lookup services. All contact details ought to be up-to-date in accordance with the policies of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the details are not accurate, the internet domain can be reported and the result could be its removal or losing its ownership. Some country-specific internet domain extensions have specific limitations regarding the change of their WHOIS details, but in the standard situation any detail can be changed openly and at any moment. Such an adjustment will show up on lookup Internet sites within twenty four hours.
