The so-called WHOIS details of any registered domain contain info about the registrar company, the registration and expiration dates, along with the names, telephone 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 obtain this information either through a command line or via one of the numerous Internet websites that offer WHOIS lookup services. All info should be up-to-date in line with the regulations of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the information is not legitimate, the domain address might be reported and the result could be its removal or losing its ownership. Several country-specific domain name extensions have specific limitations for the change of their WHOIS info, but in the standard case any detail can be edited easily and at any time. Such a change will show up on lookup Internet sites within 1 day.
