The WHOIS info of a domain name is a collection of various details that are publicly accessed via special lookup sites or a command line. The protocol that makes this possible carries the same name and you may effortlessly see the organization where a domain name has been registered, the creation, expiration and last update dates as well as the names, postal and e-mail address of the individuals listed as Registrant (owner), Administrative, Technical and Billing contacts for a particular domain name. All of this information has to be legitimate and up-to-date constantly; if not the Internet domain registration can be challenged. The latter is a policy of ICANN (the Internet Corporation for Assigned Names and Numbers), therefore you must always make certain that the WHOIS details of your domain addresses are valid. Updating the WHOIS for numerous country-code TLDs is limited, so any time you register a brand new Internet domain, you should double-check the info that you're submitting.
