> As of 28 January 2025, the Registration Data Access Protocol (RDAP) will be the definitive source for delivering generic top-level domain name (gTLD) registration information in place of sunsetted WHOIS services. RDAP offers several advantages over WHOIS including support for internationalization, secure access to data, authoritative service discovery, and the ability to provide differentiated access to registration data. RDAP was developed by the Internet Engineering Task Force.
