IPv6地址结构解析

Parsing the Addressing Architecture of IPv6

IPv6由于其近乎无限的地址空间、层次化的地址结构、高速的路由、更强的安全性、对移动性和服务质量的更好支持等特性,是替代IPv4协议、解决目前Internet面临的困境、为下一代Internet提供更好的服务和发展的最佳协议。文中详细论述了IPv6的地址体系结构,IPv6地址的种类及其与接口的关系,IPv6地址模型及IPv6地址、地址前缀、地址类型的详细格式和压缩格式的表示方法,并较完整地论述了IPv6单播地址、任意播地址和组播地址的地址格式、地址范围及其用途,对于布署IPv6网络具有指导性的作用。

IPv6 is the best protocol to replace IPv4, solve the jam of Internet facing nowadays, provide better service and development for next Internet because there is a huge address space, hiberarchy of addressing architecture, high-speed route, better security, better support for mobility and QoS. The document discourses at great length on the addressing architecture of IPv6, the addressing types of IPv6 and their connections with interface, the addressing model of IPv6 and the representation of detailed format and brief format for the IPv6's addressing, addressing prefixes and addressing types. And this specification discusses the addressing format, the addressing range and their uses of unicast, anycast and multicast. The paper has guide effect on constructing network of IPv6.
