The so-called WHOIS details of every single registered domain name contain information about the registrar company, the registration and expiration dates, in addition to 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 this info through a command line or by using one of the numerous Internet websites which provide WHOIS lookup services. All information should be up-to-date in accordance with the rules of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the information is not accurate, the internet domain might be reported and the result may be its deletion or losing its ownership. Several country-specific domain name extensions have certain limitations in connection with the editing of their WHOIS info, but in the standard scenario any detail can be edited freely and at any time. Such a change will appear on lookup Internet sites within 1 day.
