The so-called WHOIS details of every registered domain include information regarding the registrar firm, the registration and expiration dates, along with the names, phone number, postal address and e-mail address of the owner, the admin and the tech/billing person. WHOIS is a specific protocol that enables you to retrieve all of this info through a command line or by using one of the many Internet websites that offer WHOIS lookup services. All contact details should be up-to-date in accordance with 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 could be its deletion or losing its ownership. A number of country-specific domain extensions have specific limitations concerning the change of their WHOIS details, but in the typical situation any detail can be edited easily and at any moment. Such an adjustment will show up on lookup websites within twenty four hours.
