The WHOIS info of an domain name is a collection of many details which are publicly accessed through special lookup Internet sites or a command line. The protocol that 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 along with the names, postal and e-mail address of those listed as Registrant (owner), Administrative, Technical and Billing contacts for a particular Internet domain. All this information must be valid and up-to-date at all times; otherwise the domain name registration could be challenged. The latter is a policy of ICANN (the Internet Corporation for Assigned Names and Numbers), so you must always make sure that the WHOIS details of your domain addresses are accurate. Updating the WHOIS for numerous country-code TLDs is limited, so when you register a completely new domain, make sure you double-check the info you are submitting.
