Introduction

According to the Notice on Accelerating the Scale Deployment and Application of Internet Protocol Version 6 (IPv6), in order to promote the integration of IPv6 technology, In order to integrate and build an IPv6 technology system and promote the standardization of IPv6 scale deployment and application results, China has formulated a series of IPv6 technology standards.

GB/T 44866 "Technical Requirements for 4over6 for Single-Stack IPv6 Networks" was issued at a critical time for China to launch large-scale IPv6 deployment.

The standard formulated to specify the technical requirements for the 4over6 transition consists of three parts.

— Part 1: IPv4 Network Interconnection over an IPv6 Backbone. The purpose is to standardize the interconnection of IPv4 networks over an IPv6 backbone network.

— Part 2: IPv4 network interconnection based on IPv6 access network. The purpose is to standardize the use of IPv4 public land in IPv6 access network.

The two-way interconnection between users and IPv4 networks is achieved through the use of IPv4 addresses and address reuse.

— Part 3: Dynamic allocation of IPv4 addresses based on IPv6 networks. The purpose is to standardize the support of IPv4 addresses by IPv6 network users.

The mechanism of dynamic address allocation.

4over6 Technical Requirements for Single-Stack IPv6 Networks Part 1: IPv4 network interconnection based on IPv6 backbone network

1 Scope

This document specifies the technical requirements for the 4over6 mechanism for interconnecting IPv4 networks on a single-stack IPv6 backbone network.

This document is applicable to the transition phase from IPv4 network to IPv6 network, where users of IPv4 access network use the single stack IPv6 backbone network.

Scenario of interconnection using 4over6 technology.
