The so-called WHOIS details of each registered domain include information regarding the registrar organization, the registration and expiration dates, and also 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 enables you to retrieve all this info either 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 regulations of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the info is not legitimate, the domain name could be reported and the result could be its deletion or losing its ownership. Several country-specific domain address extensions have certain limitations for the modification of their WHOIS information, but in the typical scenario any detail can be edited freely and at any time. Such a modification will appear on lookup websites within twenty four hours.
