Abstract

   Many sites connected to the Internet make use of IPv4 addresses that    are not globally unique.  Examples are the addresses designated in    RFC 1918 for private use within individual sites.

   Devices in such environments may occasionally originate Domain Name    System (DNS) queries (so-called "reverse lookups") corresponding to    those private-use addresses.  Since the addresses concerned have only    local significance, it is good practice for site administrators to    ensure that such queries 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 the site.

   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 corresponding authoritative servers.  The AS112 project is named    after the Autonomous System Number (ASN) that was assigned to it.

   This document describes the steps required to install a new AS112    node and offers advice relating to such a node's operation.

   This document obsoletes RFC 6304.
