From Whois to RDAP

As seen in a LinkedIn post today, as of tomorrow, January 28 2025, the Registration Data Access Protocol (RDAP) will be the definitive source for delivering gTLD registration information in place of sunsetted WHOIS services.

ICANN states that 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 and has been offered by ICANN-accredited registrars and gTLDs since 2019.

Users are encouraged to utilize ICANN's RDAP-based Lookup service here.
