The so-called WHOIS details of every single registered domain name include info about the registrar company, the registration and expiration dates, along with the names, phone number, postal address and e-mail address of the owner, the administrator and the tech/billing person. WHOIS is a specific protocol that allows you to obtain all of this info through a command line or through one of the many Internet websites that provide WHOIS lookup services. All details must be up-to-date as per the regulations of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the information is not correct, the domain address can be reported and the result may be its removal or losing its ownership. A few country-specific domain name extensions have certain limitations regarding the change of their WHOIS details, but in the standard case any detail can be edited openly and at any time. Such an adjustment will appear on lookup websites within twenty four hours.
