The so-called WHOIS details of any registered domain include information regarding the registrar organization, the registration and expiration dates, plus the names, contact 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 get all this information through a command line or by using one of the numerous Internet websites that provide WHOIS lookup services. All info ought to be up-to-date in line with the policies of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the info is not correct, the domain address may be reported and the result might be its deletion or losing its ownership. Some country-specific domain address extensions have certain limitations for the editing of their WHOIS info, but in the typical scenario any detail can be changed openly and at any moment. Such a change will show up on lookup sites within twenty four hours.
