Abstract: Techniques for information passing for content-based source selection via DNS are described. A domain name specified in a DNS lookup request includes one or more hostname and/or subdomain values that are generated based on obfuscating a path of the object that is ultimately to be sought by the client. The authoritative DNS server can identify the desired object, and select a particular network address for the lookup response in a more intelligent manner based on characteristics of the sought object, server location availabilities and characteristics, client device characteristics, etc.
