The so-called WHOIS details of any registered domain name include info about the registrar company, the registration and expiration dates, as well as the names, telephone number, postal address and email address of the owner, the admin and the tech/billing person. WHOIS is a special protocol that enables you to get all of this information either through a command line or through one of the numerous websites that offer WHOIS lookup services. All details should be up-to-date as per the regulations of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the information is not legitimate, the internet domain might be reported and the result might be its removal or losing its ownership. A few country-specific internet domain extensions have certain limitations concerning the change of their WHOIS details, but in the standard situation any detail can be changed easily and at any moment. Such an adjustment will appear on lookup Internet sites within 1 day.
