Basic Transition Mechanisms for IPv6 Hosts and Routers (v06)
Description: This document specifies IPv4 compatibility mechanisms that can be implemented by IPv6 hosts and routers. Two mechanisms are specified, "dual stack" and configured tunneling. Dual stack implies providing complete implementations of both versions of the Internet Protocol (IPv4 and IPv6) and configured tunneling provides a means to carry IPv6 packets over unmodified IPv4 routing infrastructures. This document obsoletes RFC 2893.

Analysis on IPv6 Transition in 3GPP Networks (v11)
Description: This document analyzes the transition to IPv6 in Third Generation Partnership Project (3GPP) packet networks. These networks are based on General Packet Radio Service (GPRS) technology, and the radio network architecture is based on Global System for Mobile Communications (GSM), or Universal Mobile Telecommunications System (UMTS) / Wideband Code Division Multiple Access (WCDMA) technology. The focus is on analyzing different transition scenarios, applicable transition mechanisms and finding solutions for those transition scenarios. In these scenarios, the User Equipment (UE) connects to other nodes, e.g. in the Internet, and IPv6/IPv4 transition mechanisms are needed.

IPv6 Enterprise Network Scenarios (v05)
Description: This document describes the scenarios for IPv6 deployment within enterprise networks. It defines a small set of basic enterprise scenarios and includes pertinent questions to allow enterprise administrators to further refine their deployment scenarios. Enterprise deployment requirements are discussed in terms of coexistence with IPv4 nodes, networks and applications, and in terms of basic network infrastructure requirements for IPv6 deployment. The scenarios and requirements described in this document will be the basis for further analysis to determine what coexistence techniques and mechanisms are needed for enterprise IPv6 deployment. The results of that analysis will be published in a separate document.

Dual Stack IPv6 on by Default (v03)
Description: This document discusses problems that can occur when dual stack nodes that have IPv6 enabled by default are deployed in IPv4 or mixed IPv4 and IPv6 environments. The problems include application connection delays, poor connectivity, and network insecurity. The purpose of this memo is to raise awareness of these problems so that they can be fixed or worked around, not to try to specify whether IPv6 should be enabled by default or not.

IPv6 Neighbor Discovery On-Link Assumption Considered Harmful (v02)
Description: This document describes a change to the IPv6 Neighbor Discovery conceptual host sending algorithm. According to the algorithm, when a host's default router list is empty, the host assumes that all destinations are on-link. This is particularly problematic with IPv6-capable nodes that do not have off-link IPv6 connectivity (e.g., no default router). This document describes how making this assumption causes problems, and describes how these problems outweigh the benefits of this part of the conceptual sending algorithm.

Procedures for Renumbering an IPv6 Network without a Flag Day (v05)
Description: This document describes a procedure that can be used to renumber a network from one prefix to another. It uses IPv6's intrinsic ability to assign multiple addresses to a network interface to provide continuity of network service through a "make-before-break" transition, as well as addressing naming and configuration management issues. It also uses other IPv6 features to minimize the effort and time required to complete the transition from the old prefix to the new prefix.

IPv6 Enterprise Network Analysis (v01)
Description: This document analyzes the transition to IPv6 in enterprise networks. These networks are characterized as a network that has multiple internal links, one or more router connections, to one or more Providers, and is managed by a network operations entity. The analysis will focus on a base set of transition notational networks and requirements expanded from a previous Enterprise Scenarios document. Discussion is provided on a focused set of transition analysis required for the enterprise to transition to IPv6, assuming a dual IP layer (IPv4 and IPv6) network and node environment, within the enterprise. Then a set of transition mechanisms are recommended for each notational network.

Reasons to Move NAT-PT to Experimental (v00)
Description: 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 requests that the IETF reclassifies RFC 2766 from Standards Track to Experimental status.

ISP IPv6 Deployment Scenarios in Broadband Access Networks (v00)
Description: This document provides detailed description of IPv6 deployment and integration methods and scenarios in today's Service Provider (SP) Broadband (BB) networks in coexistence with deployed IPv4 services. Cable/HFC, BB Ethernet, xDSL and WLAN are the main BB technologies that are currently deployed, and discussed in this document. In this document we will discuss main components of IPv6 BB networks and their differences from IPv4 BB networks and how IPv6 is deployed and integrated in each of these BB technologies using tunneling mechanisms and native IPv6.
