RFC 9910: Registration Data Access Protocol (RDAP) Regional Internet Registry (RIR) Search

In plain English — editorial summary, not part of the RFC

The Registration Data Access Protocol (RDAP) is used by Regional Internet Registries (RIRs) and Domain Name Registries (DNRs) to provide access to their resource registration information. The core specifications for RDAP define basic search functionality, but there are various search options related to IP addresses, IP prefixes, and Autonomous System Numbers (ASNs), which are provided by RIRs via their WHOIS services, but for which there is no corresponding RDAP functionality. This document extends RDAP to support those search options.
