The so-called WHOIS details of each registered domain name contain information regarding the registrar company, the registration and expiration dates, along with the names, telephone number, postal address and e-mail address of the owner, the admin and the tech/billing person. WHOIS is a special protocol that enables you to retrieve all of this info either through a command line or via one of the many websites that offer WHOIS lookup services. All contact details should be up-to-date as per the policies of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the information is not accurate, the internet domain may be reported and the result could be its removal or losing its ownership. A few country-specific domain extensions have specific limitations concerning the change of their WHOIS details, but in the standard situation any detail can be edited freely and at any time. Such a change will show up on lookup sites within 24 hours.
