WHOIS records gives you organized contact data for domains,
including registrant, administrative, and technical contact information.
Per ICANN regulations, Whois databases store contact info for the owners of all registered domains. Name, address, phone number and email address are all listed. Whois also contains domain availability status, registration/expiration dates and related info. To learn more, visit our Knowledgebase article about Whois. Most domain registrars (Namecheap, for example) offer Whois Lookup options, such as the one you find above. Legally, anyone who performs a Whois search can view the stored information. If that makes you stop and wonder about the security of your own private information, please read on below about WhoisGuard privacy protection service.
