The WHOIS information of a domain is a collection of many details that are publicly accessed through special lookup Internet sites or a command line. The protocol which makes this possible carries the same name and you can effortlessly see the organization where a domain has been registered, the creation, expiration and last update dates in addition to the names, postal and e-mail address of the people listed as Registrant (owner), Administrative, Technical and Billing contacts for a specific domain. This information should be legitimate and up-to-date constantly; otherwise the domain address 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 legitimate. Updating the WHOIS for numerous country-code TLDs is limited, so whenever you register a brand new domain name, make sure you double-check the information that you are submitting.
