The WHOIS protocol is a TCP-based transaction-oriented query/response protocol that is widely used to provide information services to Internet users.

The raw WHOIS data is organized by contact data (domain name registrant contact, administrative contact, technical contact, and abuse contact) and also contains information such as the registrar, status of the domain name, and important dates.
