The protocol which makes this possible has the same name and you may 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 email address of the individuals listed as Registrant (owner), Administrative, Technical and Billing contacts for a particular Internet domain. All of this information ought to be legitimate and up-to-date at all times; if not the domain registration may be challenged. The latter is a policy of ICANN (the Internet Corporation for Assigned Names and Numbers), therefore you must always ensure that the WHOIS details of your domain addresses are accurate. Updating the WHOIS for numerous country-code TLDs is limited, so any time you register a new Internet domain, it is best to double-check the info you are submitting.
