The so-called WHOIS details of every registered domain name include info about the registrar company, the registration and expiration dates, as well as 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 lets you retrieve all this information through a command line or by using one of the many websites that provide WHOIS lookup services. All info ought to be up-to-date in line with the regulations of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the info is not legitimate, the domain might be reported and the result could be its deletion or losing its ownership. A number of country-specific domain extensions have certain limitations concerning the change of their WHOIS details, but in the standard situation any detail can be modified easily and at any time. Such a modification will appear on lookup sites within twenty four hours.
