The so-called WHOIS details of each registered domain include details about the registrar organization, the registration and expiration dates, plus 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 allows you to get all this information either through a command line or using one of the numerous Internet websites which provide WHOIS lookup services. All details must be up-to-date in accordance with the policies of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the details are not correct, the domain address may be reported and the result might be its deletion or losing its ownership. Several country-specific internet domain extensions have specific limitations for the editing of their WHOIS info, but in the standard case any detail can be changed freely and at any moment. Such a change will show up on lookup Internet sites within 24 hours.
