1.  Introduction

   Querying and retrieving registration data from registries are defined
   in Registration Data Access Protocol (RDAP) [RFC7480] [RFC7482]
   [RFC7483].  These documents do not specify where to send the queries.
   This document specifies a method to find which server is
   authoritative to answer queries for the requested scope.

   Top-Level Domains (TLDs), Autonomous System (AS) numbers, and network
   blocks are delegated by IANA to Internet registries such as TLD
   registries and Regional Internet Registries (RIRs) that then issue
   further delegations and maintain information about them.  Thus, the
   bootstrap information needed by RDAP clients is best generated from
   data and processes already maintained by IANA; the relevant
   registries already exist at [ipv4reg], [ipv6reg], [asreg], and
   [domainreg].
