摘　　要：网络的快速发展给人们的生活带来了诸多便利,但是由于接入设备的数量大幅上升,给本来就捉襟见肘的IP地址存量带来冲击。现存IPv4版本的地址数量已经接近告罄,虽然新一代的IPv6已在试验运行,但其普及还需要较长的一段时间。为了解决版本更替期间IPv4地址数量不足的问题,引入了NAT技术。文章介绍了3种类型NAT技术,阐述了其工作原理和应用,最后分析了不同NAT技术的优缺点及产生的一些问题。The rapid development of the network has brought a lot of convenience to people’s life, however, due to the sharp increase in the number of access devices, the already stretched stock of IP addresses has an impact. The number of addresses in the existing IPv4 version is close to running out, and although the new generation of IPv6 is already running on a trial basis, it will take a long time for this version to become popular. In order to solve the problem of insufficient number of IPv4 addresses during version replacement, NAT technology is introduced. This paper introduces three types of NAT technology, expounds their working principle and application, and finally analyzes the advantages and disadvantages of different NAT technologies and some problems arising from them.
