IPv4/IPv6 Intercommunication Technology Research

For IPv6 and IPv4 network seamless interconnection question, it is very essential to study IPv4/IPv6 intercommunication technology to ensure smooth transition of IPv4 to IPv6. To solve the seamless interconnection question, this article mainly researches IPv4 to IPv6 development's intercommunication question of three stages, including IPv6 based-IPv4 network interconnection, IPv4/IPv6 transparent interconnection and IPv4 IPv6-based network interconnection, and simultaneously analyzes the various interconnection stages of working ways and the suitable scopes in detail. Through choosing the technology logically,it can solve the seamless communication question.
