Reasons to Move the Network Address Translator - Protocol Translator to Historic Status

Overview

RFC 4966, “Reasons to Move the Network Address Translator - Protocol Translator to Historic Status”, is an Informational document published in July 2007 by C. Aoun, E. Davies. It obsoletes RFC 2766. The canonical text is published by the RFC Editor.

Abstract

This document discusses issues with the specific form of IPv6-IPv4 protocol translation mechanism implemented by the Network Address Translator - Protocol Translator (NAT-PT) defined in RFC 2766. These issues are sufficiently serious that recommending RFC 2766 as a general purpose transition mechanism is no longer desirable, and this document recommends that the IETF should reclassify RFC 2766 from Proposed Standard to Historic status. This memo provides information for the Internet community.
