The so-called WHOIS details of any registered domain contain info about the registrar firm, the registration and expiration dates, in addition to the names, contact number, postal address and email address of the owner, the administrator and the tech/billing person. WHOIS is a special protocol that enables you to get all of this information through a command line or by using one of the numerous websites that offer WHOIS lookup services. All contact details ought to be up-to-date in line with the regulations of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the information is not legitimate, the domain address could be reported and the result might be its deletion or losing its ownership. Several country-specific domain name extensions have specific limitations in connection with the modification of their WHOIS details, but in the standard scenario any detail can be modified openly and at any moment. Such a change will show up on lookup websites within 24 hours.
