Hi all,

We've just submitted

  draft-ietf-dnsop-as112-dname-01
  draft-jabley-dnsop-rfc6304bis-00

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!

Thanks,


Joe

> 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.
