The WHOIS information of a domain is a collection of many details which are openly accessed via specific lookup Internet sites or a command line. The protocol which makes this possible carries the same name and you may easily see the firm where an Internet domain has been registered, the creation, expiration and last update dates in addition to the names, postal and e-mail address of those listed as Registrant (owner), Administrative, Technical and Billing contacts for a specific domain name. All this info should be legitimate and up-to-date all the time; if it's not the domain name registration may be challenged. The latter is a policy of ICANN (the Internet Corporation for Assigned Names and Numbers), this means you must always ensure that the WHOIS details of your domain addresses are accurate. Updating the WHOIS for a variety of country-code TLDs is limited, so whenever you register a new domain address, you ought to double-check the information that you are submitting.
