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 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.
