摘要
由于IPv4地址匮乏,IPv4向IPv6演进已大势所趋。本文先简单阐述IPv6的基本知识,之后对现存的多种IPv4向IPv6过渡机制进行研究和比较,重点论述了隧道机制。最后对过渡期引发的安全问题进行分析。
The shortage of IPv4 address leads to the inevitable transition from IPv4 to IPv6. This paper first briefly introduces the basic knowledge of IPv6, then studies and compares some transition mechanisms which exist at present, mainly discussing the tunnel mechanism. Finally it analyzes the security issues of the transition period.
