The so-called WHOIS details of any registered domain name include details about the registrar organization, the registration and expiration dates, and also the names, contact number, postal address and email address of the owner, the admin and the tech/billing person. WHOIS is a specific protocol that lets you retrieve all of this information either through a command line or through one of the many Internet websites that offer WHOIS lookup services. All information ought to be up-to-date as per the rules of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the information is not accurate, the domain name may be reported and the result might be its removal or losing its ownership. A few country-specific domain address extensions have specific limitations regarding the editing of their WHOIS info, but in the standard case any detail can be edited openly and at any moment. Such a modification will show up on lookup Internet sites within 24 hours.
