The so-called WHOIS details of any registered domain include information about the registrar organization, the registration and expiration dates, in addition to the names, phone number, postal address and e-mail address of the owner, the admin and the tech/billing person. WHOIS is a special protocol that lets you get all this info through a command line or using one of the numerous Internet websites which provide WHOIS lookup services. All information 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 accurate, the internet domain could be reported and the result could be its deletion or losing its ownership. Several country-specific domain extensions have specific limitations concerning the editing of their WHOIS info, but in the general scenario any detail can be changed freely and at any moment. Such an adjustment will appear on lookup websites within twenty four hours.
