Overview

The Registration Data Access Protocol (RDAP) enables users to access current registration data and was created as an eventual replacement for the WHOIS protocol.  It provides a number of enhancements relative to WHOIS, such as transport security, internationalization, a structured data format, differentiated access, and extensibility.  The Internic RDAP service is compliant to ICANNs gTLD RDAP profile and you can visit https://www.icann.org/rdap for more details.

RDAP builds upon HTTP and the "REST" (REpresentational State Transfer)  architectural style. RDAP servers are web servers, and RDAP clients are web clients (which includes web browsers). RDAP responses are encoded in JSON (JavaScript Object Notation) and are machine-readable rather than human-readable.
