The Registration Data Access Protocol (RDAP) enables users to access current registration data and was created as an eventual replacement for the WHOIS protocol. RDAP was developed by the technical community in the Internet Engineering Task Force (IETF).
RDAP is a protocol that delivers registration data like WHOIS, but its implementation will change and standardize data access and query response formats.
A proposed RDAP profile for gTLD registries and registrars is currently open for Public Comment. Provide feedback on these materials here.
