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). Working Group Summary This document was discussed in depth and well-reviewed. There is some disagreement over small details, but overall WG consensus is strong to publish this document. Document Quality There are multiple, independent, interoperable implementations of this protocol today. Several service providers have announced plans to deploy or interest in deploying. Personnel The responsible Area Director is Jari Arkko, as the normal sponsor for the SOFTWIRE WG, Ralph Droms, is one of the authors of this document.
