                      AS112 Redirection Using DNAME


   AS112 provides a mechanism for handling reverse lookups on IP    addresses that are not unique (e.g., RFC 1918 addresses).  This    document describes modifications to the deployment and use of AS112    infrastructure that will allow zones to be added and dropped much    more easily, using DNAME resource records.

   This approach makes it possible for any DNS zone administrator to    sink traffic relating to parts of the global DNS namespace under    their control to the AS112 infrastructure without coordination with    the operators of AS112 infrastructure.
