                    Special Use Domain 'home.arpa.'
                       draft-ietf-homenet-dot-14

Abstract

   This document specifies the behavior that is expected from the Domain
   Name System with regard to DNS queries for names ending with
   '.home.arpa.', and designates this domain as a special-use domain
   name. 'home.arpa.' is designated for non-unique use in residential
   home networks.  Home Networking Control Protocol (HNCP) is updated to
   use the 'home.arpa.' domain instead of '.home'.

1.  Introduction

   Users and devices within a home network (hereafter "homenet") require
   devices and services to be identified by names that are unique within
   the boundaries of the homenet [RFC7368].  The naming mechanism needs
   to function without configuration from the user.  While it may be
   possible for a name to be delegated by an ISP, homenets must also
   function in the absence of such a delegation.  This document reserves
   the name 'home.arpa.' to serve as the default name for this purpose,
   with with a scope limited to each individual homenet.

   This document corrects an error in [RFC7788], replacing '.home' with
   'home.arpa.' as the default domain-name for homenets. '.home' had
   been selected as the most user-friendly option.  However, there are
   existing uses of '.home' that may be in conflict with this use:
   evidence indicates that '.home' queries frequently leak out and reach
   the root name servers [ICANN1] [ICANN2].

   In addition, it's necessary, for compatibility with DNSSEC
   (Section 6), that an insecure delegation ([RFC4035] section 4.3) be
