       Redirection Service for Registration Data Access Protocol
                     draft-ietf-weirds-redirects-01

Abstract

   The traditional WHOIS protocol has several important shortcomings,
   and over the past few years several approaches to a better
   Registration Data Access Protocol (RDAP) have been discussed and
   proposed.

   Among these shortcomings, different registries operate different
   WHOIS services.  For users this implies that several WHOIS queries to
   different registries may be necessary in order to obtain data for a
   given resource.

   This document describes a redirection service for RESTful WHOIS
   queries.  This service allows users to query a single WHOIS service
   and be redirected to the authoritative registry.

   The solution implemented proposed here applies to Regional Internet
   Registries(RIRs) and Domain Name Registries(DNRs).

Internet-Draft        RESTWhois Redirection Service             Feb 2013

1.  Introduction

   A user interested in obtaining registration information for a given
   number or domain resource normally uses the WHOIS service provided by
   the RIRs and DNRs.

   In order to avoid having to query several databases until obtaining
   an answer, some approaches have been discussed and implemented in the
   past, most notably the Joint WHOIS [lacnic-joint-whois] initiative.
   However, among other shortcomings, Joint WHOIS is implemented using
   proxies and server-side referrals.
