A system includes an analyzer module, a content request data collection module, and a domain name server. The content request data collection module is configured to receive a content request sent to a tracking address, collect content request information about the content request, and provide the content request information to the analyzer module. The domain name server is configured to receive an address request from a local domain name server for a cache server address, provide a tracking address to the local domain name server, collect address request information about the address request, and provide the address request information to the analyzer module. The analyzer module is configured to receive the address request information and the content request information, and determine properties of clients served by the local domain name server based on the address request information and the content request information. |
