Today is WHOIS sunsetting day for gTLDs, per ICANN

> 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.

Why do we need whois anymore anyway?

Itself can be setup with fake information, corporate entities hide behind their tech department.

Apart from domain expiration and list of name servers there's no point to it.
