Special-Use Domain 'home.arpa.'
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. The Home Networking Control Protocol (HNCP) is
updated to use the 'home.arpa.' domain instead of '.home'.

RFC 8375 home.arpa. May 2018
1. Introduction
Users and devices within a home network (hereafter referred to as
"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 a scope limited to each individual
homenet.
This document corrects an error in [RFC7788] by replacing '.home'
with 'home.arpa.' as the default domain name for homenets. '.home'
was 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, for compatibility with DNSSEC (see Section 6), it's
necessary that an insecure delegation (see Section 4.3 of [RFC4035])
be present for the name. There is an existing process for allocating
names under '.arpa.' [RFC3172]. No such process is available for
requesting a similar delegation in the root at the request of the
IETF, which does not administer that zone. As a result, all
