What is RDAP?

The Registration Data Access Protocol (RDAP) allows the lookup and search of domain, nameserver, and entity objects within a registry. RDAP is similar to WHOIS in that it will return information about objects within a registry. Unlike WHOIS however, RDAP responses are returned in a structured, machine readable format. Rdap responses are returned in the form of JSON.
