The so-called WHOIS details of every registered domain name include information regarding the registrar company, the registration and expiration dates, along with the names, telephone 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 all this info either through a command line or via one of the numerous Internet websites that provide WHOIS lookup services. All information should be up-to-date in line with the rules of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the information is not correct, the internet domain can be reported and the result might be its removal or losing its ownership. A number of country-specific internet domain extensions have specific limitations regarding the editing of their WHOIS details, but in the general case any detail can be edited openly and at any time. Such an adjustment will show up on lookup websites within twenty four hours.
