The so-called WHOIS details of every registered domain include info about the registrar company, the registration and expiration dates, and also the names, contact number, postal address and e-mail address of the owner, the admin and the tech/billing person. WHOIS is a specific protocol that permits you to retrieve all of this information through a command line or using one of the many Internet websites that provide WHOIS lookup services. All information should be up-to-date in line with the policies of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the details are not accurate, the domain name can be reported and the result could be its removal or losing its ownership. A number of country-specific domain extensions have specific limitations in connection with the modification of their WHOIS info, but in the standard scenario any detail can be edited openly and at any time. Such a modification will show up on lookup Internet sites within 1 day.
