The so-called WHOIS details of any registered domain include info about the registrar company, the registration and expiration dates, plus the names, telephone number, postal address and email address of the owner, the administrator and the tech/billing person. WHOIS is a special protocol that permits you to obtain all this information either through a command line or through one of the many Internet websites that offer WHOIS lookup services. All details should be up-to-date in accordance with the rules of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the details are not legitimate, the domain name may be reported and the result could be its deletion or losing its ownership. Several country-specific domain extensions have certain limitations in connection with the change of their WHOIS info, but in the general situation any detail can be edited openly and at any time. Such a change will appear on lookup Internet sites within 24 hours.
