RDAP

RDAP (Registration Data Access Protocol) is a communications protocol designed for querying registration data (e.g., domain names, IP addresses, autonomous system numbers) on the Internet. Standardized by the IETF in 2015, RDAP is a modern successor to WHOIS, offering structured, machine-readable (JSON) responses and supporting automated queries, enhanced access control, and robust authentication. It is ideal for network engineers, security researchers, domain administrators, and organizations requiring standardized access to domain and network resource registration data.
