The so-called WHOIS details of every registered domain name contain 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 get this information through a command line or using one of the numerous Internet websites that provide WHOIS lookup services. All info must be up-to-date in line with the rules of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the info is not accurate, the domain could be reported and the result might be its removal or losing its ownership. A few country-specific internet domain extensions have certain limitations regarding the modification of their WHOIS details, but in the typical case any detail can be changed easily and at any time. Such a change will show up on lookup websites within a day.
