域名系统（DNS）是当今互联网通信的基本组件，为数十亿用户和众多应用程序提供域名到IP的转换。然而，DNS的操作故障并不罕见，有时会导致严重的后果，如互联网中断。为了更好地了解DNS操作故障，以前的工作检查了大规模的DNS日志（互联网用户和DNS服务器之间的DNS查询和响应），但DNS日志无法提供故障的全面视图（例如，在域注册商的错误），并解释在更细的粒度失败。在本文中，我们试图从另一个数据源，DNS服务提供商建立的支持论坛来评估DNS操作故障。具体来说，我们挖掘了4个DNS论坛，抓取了超过10000个帖子和50000个回复。有了我们开发的新分析框架，我们能够按不同类别（例如，一般问题、问题位置和记录类型），并获得有关用户如何以及为何遇到DNS故障的新见解。最后，我们为DNS服务提供商和用户提供建议，以减轻DNS操作问题。
Domain Name System (DNS) is a fundamental component for today’s Internet communications, enabling the domain-to-IP translations for billions of users and numerous applications. Yet, the operational failures of DNS are not rare and sometimes lead to severe consequences like Internet outages. To gain a better understanding of DNS operational failures, previous works examined large-scale DNS logs (DNS queries and responses between Internet users and DNS servers), but the DNS logs cannot offer a comprehensive view of the failures (e.g., errors at domain registrars) and explain the failures at a finer grain. In this paper, we try to assess DNS operational failures from another data source, the supporting forums built by DNS service providers. Specifically, we mined 4 DNS forums and crawled more than 10000 posts and 50000 replies. With a new analysis framework developed by us, we are able to tag the forum posts by different categories (e.g., general concerns, issue locations, and record types), and gain new insights regarding how and why users encounter DNS failures. In the end, we offer suggestions to DNS service providers and users to mitigate DNS operational issues.
