The so-called WHOIS details of each registered domain contain information about the registrar firm, the registration and expiration dates, in addition to the names, telephone number, postal address and email address of the owner, the admin and the tech/billing person. WHOIS is a specific protocol that allows you to obtain all this info through a command line or via one of the many Internet websites which provide WHOIS lookup services. All information ought to be up-to-date in accordance with the regulations of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the information is not accurate, the internet domain could be reported and the result might be its removal or losing its ownership. Several country-specific domain extensions have certain limitations for the editing of their WHOIS details, but in the general scenario any detail can be changed freely and at any moment. Such a change will appear on lookup websites within 1 day.
