Hi all,

We've just submitted


which together specify an approach to extend the current AS112 project to be able to sink queries from arbitrary zones, whilst still supporting existing AS112 semantics.

We hope to present a brief overview of the approach in London.

Reactions and reviews of the two documents would be most welcome!

> 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 IN-ADDR.ARPA authoritative servers.  The AS112 project is named
>   after the Autonomous System Number (ASN) that was assigned to it.
>   The AS112 project does not accommodate the addition and removal of
>   DNS zones elegantly.  Since additional zones of definitively local
>   significance are known to exist, this presents a problem.  This
>   document describes modifications to the deployment and use of AS112
>   infrastructure that will allow zones to be added and dropped much
>   more easily.
