The so-called WHOIS details of every registered domain name include info about the registrar organization, the registration and expiration dates, in addition to the names, telephone number, postal address and e-mail address of the owner, the admin and the tech/billing person. WHOIS is a special protocol that enables you to obtain all of this info either through a command line or through one of the numerous sites that provide WHOIS lookup services. All info must 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 domain address can 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 modification of their WHOIS information, but in the typical case any detail can be edited freely and at any moment. Such a change will appear on lookup websites within 1 day.
