Technical Summary

   This document revisits the dual-stack model and introduces the dual-
   stack lite technology aimed at better aligning the costs and benefits
   of deploying IPv6. Dual-stack lite enables a broadband service
   provider to share IPv4 addresses among customers by combining two
   well-known technologies: IP in IP (IPv4-in-IPv6) and Network Address
   Translation (NAT).

   protocol today. Several service providers have announced plans to deploy
   or interest in deploying.
