Systems and Method to Discover Clients Associated with Local Domain Name Server Using Sampling

摘要

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.

1. A system for discovering clients, the system comprising:
a memory for storing instructions; a processor that executes the instructions to perform operations, the operations comprising:
receiving, in response to a first address request from a local domain name server for an internet protocol address of a cache server, address request information that is associated with a tracking address provided to the local domain name server, wherein the tracking address is provided to the local domain name server in response to a predefined request interval, wherein the predefined request interval indicates a rate at which the tracking address is provided to the local domain name server per a given quantity of address requests;determining client information associated with a client system based on the address request information and based on content request information associated with a content request sent to the tracking address; andassociating the client system with the local domain name server based upon the tracking address.
