互联网采用的是 TCP/IP 协议,核心协议之一就是 IP 地址编码协议。目前 IPv4的地址是32位编码,而以后将要采用的IPv6的地址是128位编码,能产生2的128次方个 IP 地址,其资源几乎是无穷的。美国1996年启动下一代互联网研究计划 NGI,中国最早从1998年开始跟踪。中国教育和科研计算机网(CERNET)研究下一代互联网的历程,几乎就是中国下一代互联网研究与建设历程的写照。1998年:4月,CERNET 建立我国第一个 IPv6试验网,组建了第一个连接国内八大城市的 IPv6试验床,获得中国第一批 IPv6
The Internet uses the TCP / IP protocol, one of the core protocols is the IP address encoding protocol. At present, the address of IPv4 is a 32-bit code, and the IPv6 address to be adopted in the future is a 128-bit code, which can generate 128 times of 2 IP addresses and has almost unlimited resources. The United States started NGI, a next-generation Internet research project, in 1996, and China started tracking as early as 1998. The history of the next generation Internet research by China Education and Research Network (CERNET) is a portrayal of the next generation of Internet research and construction in China. 1998: In April, CERNET established China’s first IPv6 trial network and formed the first IPv6 test bed that connects the eight major cities in China, winning the first batch of IPv6 in China
