The WHOIS info of a domain is a collection of numerous details which are freely accessed via special lookup sites or a command line. The protocol which makes this possible has the same name and you can effortlessly see the organization where a domain name 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 address. All this info must be correct and up-to-date all the time; otherwise the domain name registration could be challenged. The latter is a policy of ICANN (the Internet Corporation for Assigned Names and Numbers), this means you should always make certain that the WHOIS details of your domain addresses are accurate. Updating the WHOIS for a number of country-code TLDs is limited, so whenever you register a brand new domain, make sure you double-check the information that you are submitting.
