The WHOIS info of a domain is a collection of numerous details that are publicly accessed using specific lookup Internet sites or a command line. The protocol which makes this possible has the same name and you may effortlessly see the organization through which an Internet domain has been registered, the creation, expiration and last update dates in addition to the names, postal and e-mail address of the people listed as Registrant (owner), Administrative, Technical and Billing contacts for a particular domain. This info should be correct and up-to-date all the time; otherwise the domain registration can be challenged. The latter is a policy of ICANN (the Internet Corporation for Assigned Names and Numbers), therefore you should always make sure that the WHOIS details of your domain names are legitimate. Updating the WHOIS for numerous country-code TLDs is limited, so any time you register a completely new Internet domain, it is best to double-check the information that you are submitting.
