> Why would DNS have "optimized, localized results"?
Any content that is CDN-based (which is most content) dynamically responds to DNS queries based on network and geographic location - to support CDN localization. In this way, Akamai for example knows the end user is in Boston on a Comcast network and will send the recursive DNS server a dynamic response that points to a directly-connected local-to-Boston content server.
