       Finding the Authoritative Registration Data (RDAP) Service
                   draft-ietf-weirds-bootstrap-00.txt

Abstract

   This document specifies a method to find which Registration Data
   Access Protocol (RDAP) server is authoritative to answer queries for
   a requested scope, such as domain names, IP addresses or Autonomous
   System numbers, using data available in IANA registries.

1.  Introduction

   Querying and retrieving registration data from registries are defined
   in the Registration Data Access Protocol(RDAP)[I-D.ietf-weirds-rdap-q
   uery][I-D.ietf-weirds-using-http][I-D.ietf-weirds-json-response].
   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.

   The proposed mechanism is based on that allocation data for domain
   names and IP addresses are maintained by IANA, are publicly available
   and are in a structured format.  The mechanism assumes some data
   structure within these registries and request IANA to modify or
   create these registries for the specific purpose of RDAP use.  An
   RDAP client fetches the registries, extract the data and then do a
   match with the query data to find the authoritative registration data
   server and appropriate query base URL.

2.  Domain Name RDAP Registry

   The domain names authoritative registration data service is found by
   doing the longest match of the target domain name with the values of
   the Domain column in the IANA Domain Name RDAP registry as defined in
   section Section 9.  The value of the "RDAP URL" column is the base
   RDAP url as described in [I-D.ietf-weirds-rdap-query].

   For example, a RDAP query for example.com matches the .com entry in
   the Domain column of the registry.  The RDAP server URL for this
   address is located in the corresponding "RDAP URL" column for that
   entry, which could be http://rdap.example.org/rdap.  Therefore the
