In both of the above cases, the owner (e.g., CNN, YouTube, or Zynga) of the content and the organiza- tion serving it (e.g., Akamai, Limelight, or Amazon EC2) are decoupled, thus making it harder to understand the associ- ation between the content, owner, and the host where the content resides. This has created a tangled world wide web that is very hard to unwind, impairing ISPs’ and network administrators’ capabilities to control the traffic flowing in their networks. &lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span&gt;In this paper, we present DN-Hunter, a system that lever- ages the information provided by DNS traffic to discern the tangle. Parsing through DNS queries, DN-Hunter tags traf- fic flows with the associated domain name. This association has several applications and reveals a large amount of use- ful information: (&lt;/span&gt;&lt;span&gt;i&lt;/span&gt;&lt;span&gt;) Provides a fine-grained traffic visibility even when the traffic is encrypted (i.e., TLS/SSL flows), thus enabling more effective policy controls, (&lt;/span&gt;&lt;span&gt;ii&lt;/span&gt;&lt;span&gt;) Identifies flows even before the flows begin, thus providing superior net- work management capabilities to administrators, (&lt;/span&gt;&lt;span&gt;iii&lt;/span&gt;&lt;span&gt;) Un- derstand and track (over time) different CDNs and cloud providers that host content for a particular resource, (&lt;/span&gt;&lt;span&gt;iv&lt;/span&gt;&lt;span&gt;) Discern all the services/content hosted by a given CDN or cloud provider in a particular geography and time interval, and (&lt;/span&gt;&lt;span&gt;v&lt;/span&gt;&lt;span&gt;) Provides insights into all applications/services run- ning on any given layer-4 port number. &lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span&gt;We conduct extensive experimental analysis and show re- sults from real traffic traces (including FTTH and 4G ISPs) that support our hypothesis. Simply put, the information provided by DNS traffic is one of the key components re- quired for understanding the tangled web, and bringing the ability to effectively manage network traffic back to the op- erators.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</style></abstract><num-vols><style face="normal" font="default" size="100%">1</style></num-vols></record></records></xml>
