The WHOIS information of a domain is a collection of various details that are publicly accessed using specific lookup Internet sites or a command line. The protocol that makes this possible bears the same name and you could effortlessly see the company through which a domain name has been registered, the creation, expiration and last update dates together with the names, postal and email address of those listed as Registrant (owner), Administrative, Technical and Billing contacts for a specific Internet domain. All this info ought to be correct and up-to-date at all times; if it's not the Internet domain registration could be challenged. The latter is a policy of ICANN (the Internet Corporation for Assigned Names and Numbers), therefore you should always make certain that the WHOIS details of your domains are accurate. Updating the WHOIS for several country-code TLDs is limited, so whenever you register a completely new domain name, you should double-check the info that you are submitting.
