Abstract:
   Dual-Stack Lite (RFC 6333) describes an architecture for transporting
   IPv4 packets over an IPv6 network.  This document specifies an
   extension to DS-Lite called Lightweight 4over6 which moves the
   Network Address and Port Translation (NAPT) function from the
   centralized DS-Lite tunnel concentrator to the tunnel client located
   in the Customer Premises Equipment (CPE).  This removes the
   requirement for a Carrier Grade NAT function in the tunnel
   concentrator and reduces the amount of centralized state that must be
   held to a per-subscriber level.  In order to delegate the NAPT
   function and make IPv4 Address sharing possible, port-restricted IPv4
   addresses are allocated to the CPEs.
