摘　　要：在IPv4网络向IPv6网络过渡过程中,已经出现了多种过渡技术和方案,网络地址转换-协议转换NAT-PT是IPv4/IPv6过渡过程中的一种关键技术。为了达到两种网络的无缝连接的目的,通过对NAT-PT过渡原理的分析以及对域名服务-应用层网关DNS-ALG工作机制的研究,采用了结合DNS-ALG的动态NAT-PT过渡方案,借助Cisco模拟器GNS3模拟实现了IPv6网络通过域名与IPv4网络的互通,并对该技术的工作机制进行了分析和对实验结果进行了抓包分析和验证。There exist a variety of transition technologies and programs from IPv4 network to IPv6 network,and NAT-PT（Net Address Translation-Protocol Translation） is a key technology in IPv4/IPv6 transition process.In order to achieve seamless connectivity of these two types of networks.Based on study of NAT-PT transition principle and work mechanism of DNS-ALG（Domain Name Service-Application Layer Gateway）,by adopting dynamic NAT-PT transition program in combination of DNS-ALG,the inter-communication between IPv6 network and IPv4 network through domain names is implemented with Cisco simulator GNS3.Finally,the working mechanism of this technology is analyzed,and the test result is captured for analysis and verification.
