The WHOIS info of a domain name is a collection of various details which are freely accessed through special lookup websites or a command line. The protocol which makes this possible bears the same name and you can effortlessly see the organization through which a domain 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 specific domain. This information ought to be correct and up-to-date at all times; otherwise the domain address registration may 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 names are accurate. Updating the WHOIS for a variety of country-code TLDs is limited, so when you register a brand new domain name, you ought to double-check the info you are submitting.
