Through a large number of books gathering information and Internet information, a summary of IPV6 to IPV4 means of munication and munication tunneling technology to give an indepth research. Known as the IPv6 nextgeneration Internet to achieve agreement with the previous generation of the Internet, how to plete the first generation of munication protocol from the secondgeneration munication protocol to the transition, which are to be discussed in this article. How to achieve IPv6 through IPv4 network munications,IPv6 proto
