                      draft-manderson-rdns-xml-01

Abstract

   This document defines an Extensible Markup Language (XML) Schema for
   Reverse DNS Management in a tightly controlled Representational State
   Transfer (REST) environment.  This document describes a schema that
   has been developed and deployed by ICANN in a "RESTful" based system
   since 2011 and is being used by the registries responsible for
   reverse DNS (rDNS) delegations underneath IN-ADDR.ARPA and IP6.ARPA
   through an X.509 certificate mediated HTTPS transaction.

2.  Introduction

   This document defines an Extensible Markup Language (XML) Schema for
   Reverse DNS Management in a tightly controlled Representational State
   Transfer (REST) [REST] environment.  This document describes a schema
   that has been developed and deployed by ICANN in a "RESTful" based
   system since 2011 and is being used by the registries responsible for
   reverse DNS (rDNS) delegations underneath IN-ADDR.ARPA [RFC1034] and
   IP6.ARPA [RFC3152] through an X.509 [RFC5280] certificate mediated
   HTTPS [RFC2818] transaction.

   As DNSSEC [RFC4033]  adoption progresses the necessity to interact
   with a delegation in the IN-ADDR.ARPA and IP6.APRA zones becomes more
   frequent given that updates to DS records in the parent zone for
   child delegations follow the key rollover and expiry of the child
   zone.  The modification of such critical areas at a relative high
   frequency requires a system that allows the administrative holders of
   such delegations to make such changes in a secure and trustworthy
   manner where the chain of trust for submitting the necessary
   information remains unbroken between the IN-ADDR.ARPA and IP6.APRA
   zone maintainers and the zone customers.

   At the request of the Regional Internet Registries to automate
   reverse DNS updates with ICANN, a REST based HTTPS service was
   deployed that:
