 Nameservers for the Address and Routing Parameter Area ("arpa") Domain

Abstract

   This document describes revisions to operational practices to
   separate function of the "arpa" top-level domain in the DNS from its
   historical operation alongside the DNS root zone.

1.  Introduction

   The "arpa" top-level domain [RFC3172] is designated as an
   "infrastructure domain" to support techniques defined by Internet
   standards.  Zones under the "arpa" domain provide various mappings,
   such as IP addresses to domain names and E.164 numbers to URIs.  It
   also contains special use names such as "home", which is a non-unique
   name used in residential home networks.

   Historically, the "arpa" zone has been hosted on almost all of the
   root name servers, and [RFC3172] envisages the "arpa" domain to be
   "sufficiently critical that the operational requirements for the root
   servers apply to the operational requirements of the "arpa" servers".
   To date, this has been implemented by serving the "arpa" domain
   directly on a subset of the root server infrastructure.

   This bundling of root server and "arpa" server operations has
   entwined management of the zones contents and their infrastructure.
   As a result, some proposals under consideration by the IETF involving
   the "arpa" zone have been discarded due to the risk of conflict with
   root operations.

   The separation described in this document resolves operational
   impacts of synchronizing edits to the root zone and the "arpa" zone
   by eliminating the current dependency and allowing more tailored
   operations based on the unique requirements of each zone.
