WHOIS is a TCP-based transaction-oriented query/response protocol that is widely used to provide information services to Internet users. While originally used to provide 'white pages' services and information about registered domain names, current deployments cover a much broader range of information services. The protocol delivers its content in a human-readable format. The WHOIS protocol is documented in RFC 3912
