Abstract
A DNS nameserver processes requests for domain name information based on subscriber identifiers, and optionally subscriber information. Based on a subscriber identifier, requests for a target domain name may generate a DNS response with domain name information for a proxy service. Techniques are provided to seamlessly and transparently authenticate a subscriber at the proxy service. The proxy service generates a redirect with a unique domain name including a tracking identifier in response to requests for a target domain name. The nameserver receives a request associated with the unique domain name. The nameserver responds with domain name information of the proxy service and generates a message to the proxy service mapping the tracking identifier to the subscriber identifier. The client then generates a request to the proxy service that includes the tracking identifier. The proxy service uses the mapping from the nameserver to authenticate the corresponding subscriber identifier.
