The so-called WHOIS details of every single registered domain include details about the registrar firm, the registration and expiration dates, along with the names, contact number, postal address and e-mail address of the owner, the admin and the tech/billing person. WHOIS is a special protocol that permits you to get all this info either through a command line or using one of the numerous sites which provide WHOIS lookup services. All contact details must be up-to-date as per the policies of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the info is not legitimate, the domain address can be reported and the result might be its removal or losing its ownership. A number of country-specific domain address extensions have specific limitations regarding the editing of their WHOIS information, but in the standard case any detail can be edited easily and at any time. Such an adjustment will appear on lookup Internet sites within 1 day.
