Abstract
Comprises identifying an end point or content server that can best serve an end user that sent a DNS request to an ISP DNS resolver, given a geographically distributed network of end points. In particular, the method further comprises using the end points themselves and a tracker to identify and notify to the end user the IP addresses of the least-loaded and closest end points that can best serve the content request.
