本文主要介绍了IPv6中的无状态地址配置的过程,并描述了这个过程中所涉及到的邻居发现协议消息,以及节点上要运行的DAD进程。IPv6中的无状态地址自动配置机制所要实现的目标是:不需要手动配置连接到网络上的主机,甚至在具有多个网络和路由器的大的站点中,也不需要DHCP服务器来配置主机。这正是IPv6在地址自动配置方面所增加的新功能;在文章结尾对IPv6的地址自动配置目前的发展趋势作了展望。
This paper mainly introduces the process of stateless address configuration in IPv6, and describes the neighbor discovery protocol messages involved in this process and the DAD processes to be run on the nodes. The goal of the stateful address autoconfiguration mechanism in IPv6 is that it does not require manual configuration of hosts connected to the network and does not require a DHCP server to configure the host even on large sites with multiple networks and routers. This is exactly what IPv6 adds to address autoconfiguration; at the end of this article, we look forward to the current trend of IPv6 address autoconfiguration.
