IPv6是“Internet Protocol Version6”的缩写,它是由IETF设计的用来替代现行的IPv4协议的一种新的IP协议。IPv6是为了解决IPv4所存在的一些问题和不足而提出的,同时它还在许多方面提出了改进,例如路由方面、自动配置方面。经过一个较长的IPv4和IPv6共存的时期,IPv6最终会完全取代IPv4在互联网上占据统治地位。中国IPv6的发展将会给全球通信业带来深远影响。 IPv6 is an acronym for “Internet Protocol Version 6,” a new IP protocol designed by the IETF to replace the current IPv4 protocol. IPv6 is proposed to solve some problems and deficiencies existing in IPv4. At the same time, it proposes improvements in many aspects, such as routing and auto-configuration. After a long period of coexistence between IPv4 and IPv6, IPv6 will eventually completely replace IPv4’s dominance over the Internet. The development of IPv6 in China will bring far-reaching impact on the global communications industry.
