中国大陆IPv4地址分布影响因素分析及IPv6地址分配建议

Impact Factors Analysis of the Distribution of IPv4 Addresses and Suggestions on the Allocation of IPv6 Addresses in China's Mainland

网际协议(Internet Protocol,IP)地址是因特网的一种关键基础资源,是连接和使用因特网必不可少的要素之一.由于在网际协议第4版(IPv4)的设计及其地址分配之初没有预料到因特网规模的迅猛增长,产生了因地址分配策略不合理而无法进行路由聚合从而影响网络性能等问题.IPv4地址已经分配完毕,由IPv4向IPv6过渡不可避免,现在还处于过渡的早期阶段,本文对我国大陆地区IPv4地址的分布及其影响因素进行分析研究,提出了指导我国大陆地区IPv6地址的申请和分配的建议,避免再次出现一些由IP地址分配产生的问题.

Internet Protocol （IP） address is one of key basic resources on Internet and one of necessary elements for accessing Inter- net. At the beginning of design and its address allocation of Internet Protocol version 4 （ IPv4 ） ,it has not been anticipated that the size of Internet could have such a rapid growth, the policy for address allocation is not very reasonable, which produces problems such as that some routes cannot be aggregated and results in degrading the routing performance of Internet. All of IPv4 addresses have been al- located. It is inevitable of transiting from IPv4 to IPv6, and is still at the early stage of this transition. In this paper, we study the distri- bution of IPv4 address in our mainland area, analysis its impact factors, and propose some suggestions on guiding the application and assignment of IPv6 address in the China's Mainland, avoiding problems that result from IP address assignment.
