The WHOIS info of a domain name is a collection of a variety of details that are openly accessed through specific lookup Internet sites or a command line. The protocol which makes this possible carries the same name and you may effortlessly see the firm where an Internet domain has been registered, the creation, expiration and last update dates as well as the names, postal and e-mail address of those listed as Registrant (owner), Administrative, Technical and Billing contacts for a specific domain address. All of this information should be legitimate and up-to-date all the time; if it's not the domain address registration could be challenged. The latter is a policy of ICANN (the Internet Corporation for Assigned Names and Numbers), therefore you must always make sure that the WHOIS details of your domains are legitimate. Updating the WHOIS for a variety of country-code TLDs is limited, so any time you register a brand new Internet domain, you should double-check the information you're submitting.
