摘　　要：随着IPv6的兴起,研究如何从IPv4渐进地,无缝地过渡到IPv6成了一个热门的话题。在过渡的初期,孤立的IPv6站点之间的相互通信是一个急需解决的问题。论文深入探讨了用于解决该问题的6to4隧道技术的核心思想,运作过程。该技术简单易行,克服了配置隧道技术所带来的路由低效,维护复杂等不足之处。最后,对6to4隧道技术在现有隧道技术中的地位和作用也给出了评价。With the rise of IPv6,how to transit from IPv4to IPv6gradually and seamlessly has been one of the hottest subjects in the networking community.During the early phases,one of the critical problems is how to provide a solution for isolated IPv6sites to communicate with each other.This paper discusses elaborately the core idea,function and oper-ation of6to4tunneling technique,which overcomes the routing inefficiency and maintenance complexity brought by the configured tunneling technique.The position of6to4technique among all the current tunneling techniques is also pre-sented at the end of this paper.
