　　速变(Fast-Flux)服务网络通过返回不断变化的DNS解析结果，以大量被攻陷主机的IP地址作为服务地址，利用被攻陷主机进行重定向形成服务网络。长时间跟踪并记录了分布在全球6大洲的300个DNS服务器对23000多个域名的解析结果。根据DNS解析数据，文章对比其他研究成果从多个维度对Fast-Flux恶意域名和Fast-Flux服务网络的行为特征进行了全面讨论，并进一步开展特征辨识度分析。关于 Fast-Flux 服务网络行为特征的分析揭示了FFSN新的行为变化，为恶意域名检测、网络资源保护等提供了依据。

Fast-Flux Service Network is a network of compromised computer systems with public DNS records that are constantly changing. In this paper, we collected DNS data from 300 different domain servers spanning 6 continents. Our engines worked for over 1600 hours on more than 23000 domains. With the tremendous DNS reply data, we are able to analyze the behavior of Fast-Flux Domain and Fast-Flux Service Network through different dimensions, and locate the most distinguishing features. This paper helps to reveal new features compared with previous researches, and verify the dynamic nature of Fast-Flux Service Network. Behavioral analysis of Fast-Flux Service Network also provides a view for malicious domain detection and network resource protection.
