WHOIS Sunset: RDAP Takes Over gTLD Registration Data

Starting January 28, 2025, the Registration Data Access Protocol (RDAP) becomes the primary source for generic top-level domain (gTLD) registration information, replacing the sunsetting WHOIS service. RDAP offers improvements such as internationalization support, secure access, authoritative service discovery, and differentiated data access. Developed by the IETF, RDAP has been used by ICANN-accredited registrars since 2019. Users can access data via ICANN's RDAP lookup service (https://lookup.icann.org/en) or its open-source command-line client. For non-public data, use the Registration Data Request Service (RDRS) or contact the registrar directly.
