1.  Introduction

   The RDAP protocol described in RFCs 7480-7484 supports nameserver
   object lookup based on the name of the nameserver (see section 3.1.4
   of [RFC7482]), therefore it may not be possible to retrieve the
   registration information of a particular nameserver object sharing
   the name with other nameserver objects.

   This document describes a Registration Data Access Protocol (RDAP)
   extension that may be used to retrieve the registration information
   of a particular nameserver object sharing the name with other
   nameserver objects.

   This specification is intended to be used by Domain Name Registries
   (DNRs) that support the coexistence of multiple external hosts (see
   [RFC5732]) sharing the same name in the repository.

2.  Terminology

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].

3.  RDAP Conformance object

   A server that conforms to this specification MUST include the string
   literal "rdap_nameservers_sharing_name" in the "rdapConformance"
   member of the topmost JSON object of all responses provided by the
   server.

   An example of a rdapConformance data structure including this
   extension:

     "rdapConformance" :
     [
      "rdap_level_0",
      "rdap_nameservers_sharing_name"
     ]
