The so-called WHOIS details of every single registered domain contain details about the registrar organization, the registration and expiration dates, plus the names, phone number, postal address and email address of the owner, the admin and the tech/billing person. WHOIS is a specific protocol that lets you obtain this information either through a command line or by using one of the many Internet websites that offer WHOIS lookup services. All info ought to be up-to-date in line with the policies of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the info is not legitimate, the domain name might be reported and the result may be its deletion or losing its ownership. A number of country-specific domain name extensions have certain limitations in connection with the modification of their WHOIS info, but in the standard scenario any detail can be changed easily and at any time. Such a modification will show up on lookup Internet sites within a day.
