摘要
IP定位技术就是确定Internet中IP设备的地理位置,它可以帮助网络应用改善性能、提高安全性以及提供新的服务.首先概述了IP定位技术的基本概念和应用情况;然后,将现有定位算法分为独立于客户端和基于客户端两类定位算法,并对每一类算法中的典型算法进行了具体分析,讨论了隐私保护技术和新技术的影响;最后,对现有的IP定位算法进行了综合对比,指出了IP定位技术的研究方向.
IP geolocation aims at determining the geographic location of an Internet host, which can improve the performance and security of the Internet application, and bring about novel services. This paper firstly illustrates the concept and applications of the IP geolocation, and then categorizes current typical IP address geolocation algorithms into two classes, namly, client-independent geolocation algorithms and client-dependent geolocation algortithms. Next, the main ideas of the representative algorithms of each class are illustrated, and the privacy protection techniques and the influence of new techniques are discussed. Finally, a comprehensive comparison is made on the IP geolocation algorithms and systems, and the future trends of the IP geolocation are discussed.
