摘　　要：介绍了IPv4、IPv6与IPv9的特点,并在地址空间、域名服务、移动性、安全性、QoS、自动配置、应用范围以及发展趋势等几个方面,对三者加以比较研究,分析其优劣。指出与IPv4相比,IPv6彻底解决了地址空间耗尽和路由表爆炸等问题,而且为IP协议注入了新的内容,使网络安全、移动主机以及Qos成为IP协议的有机组成部分。IPv6在国际上已经占据主流地位,以IPv6代替IPv4是必然的,其规模与效益会远远领先于IPv9。而IPv9尚未在国际上得到认可,在标准竞争中将处于劣势。This paper introduces the characteristics of IPv4, IPv6 and IPv9, and compares them in several aspects, such as address space and domain name service, mobility support, built-in security features, QoS, auto-configuration, applications and sponsors. It points out that IPv6, compared with IPv4, adds new ideas to IP protocol by making network security, mobil host and Qos become the parts of IP protocol. IPv6 is becoming the trend in the world, so it is inevita- ble to replace IPv4 and becomes more advanced than IPv9, which is still unaccepted internationally.

关 键 词：IPV4 IPV6 IPv9 标准
