With the development of , based on IPv4 has exposed much disadvantage in practical application,such as the address space exhausting day by day, service security, questions restrict the development of badly,and these questions are pletely and effectively only through the construction of next generation ,so IPv6 has the next edition of protocol,IPv6 replacing IPv4 es inevitably trend of technology,the new characteristic of IPv6 protocol will offer broader prospect and perfect wupport for application and ,because of the difference of head characteristic and address format,they are unable to be must be solved how to transit to IPv6 gradually and smoothly,as the next Protocol,IPv6 have already got much application in ,but a lot of questions must be improved and perfected,plete transition from IPv4 to IPv6 need very long time still,work structure will have one’s own transition policy too.
In this paper, combining the research and significance of the background to understand the importance of this issue, Then through analyzing the basic principles of IPv6, network architecture, technology transition. For the IPv6 protocol characteristics, the analysis of three transitional technology, and predicts its development prospects. The paper concludes that the transition to IPv6 work strategy.
