The so-called WHOIS details of every single registered domain name include info about the registrar firm, the registration and expiration dates, and also the names, phone number, postal address and email address of the owner, the admin and the tech/billing person. WHOIS is a specific protocol that enables you to obtain this info either through a command line or by using one of the numerous websites which provide WHOIS lookup services. All contact details must be up-to-date in accordance with the regulations of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the details are not legitimate, the domain name could be reported and the result could be its removal or losing its ownership. Some country-specific domain extensions have certain limitations regarding the editing of their WHOIS information, but in the typical scenario any detail can be edited openly and at any moment. Such an adjustment will appear on lookup Internet sites within twenty four hours.
