Many sites connected to the Internet make use of IPv4 addresses which
are not globally unique. Examples are the addresses designated in
RFC1918 for private use within individual sites.
Devices in such environments may occasionally originate reverse DNS
queries corresponding to those private-use addresses. Since the
addresses concerned have only local significance, it is good practice
for site administrators to ensure that they are answered locally.
However, it is not uncommon for such queries to follow the normal
delegation path in the public DNS instead of being answered within
It is not possible for public DNS servers to give useful answers to
such queries. In addition, due to the wide deployment of private-use
addresses and the continuing growth of the Internet, the volume of
such queries is large and growing. The AS112 project aims to provide
a distributed sink for such queries in order to reduce the load on
the root and IN-ADDR.ARPA authority servers.
This document describes the steps required to install a new AS112
node, and offers advice relating to such a node's operation.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
