The so-called WHOIS details of every single registered domain contain information about the registrar firm, the registration and expiration dates, in addition to the names, contact number, postal address and email address of the owner, the administrator and the tech/billing person. WHOIS is a special protocol that enables you to retrieve all this info either through a command line or using one of the numerous websites that provide WHOIS lookup services. All details ought to be up-to-date as per the rules of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the information is not accurate, the domain address can be reported and the result might be its removal or losing its ownership. Some country-specific internet domain extensions have specific limitations concerning the modification of their WHOIS info, but in the typical scenario any detail can be modified freely and at any moment. Such an adjustment will show up on lookup websites within twenty four hours.
