The so-called WHOIS details of each registered domain name include details about the registrar company, the registration and expiration dates, along with the names, contact 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 retrieve all this information either through a command line or using one of the numerous Internet websites that provide WHOIS lookup services. All details 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 address might be reported and the result might be its removal or losing its ownership. A few country-specific domain address extensions have certain limitations regarding the editing of their WHOIS information, but in the general case any detail can be edited freely and at any time. Such a modification will appear on lookup websites within 1 day.
