Abstract:
Systems, methods, apparatuses, and software for a content delivery network that caches content for delivery to end user devices is presented. In one example, a method includes establishing domain name relationships for use by a top-level DNS to recurse DNS queries to a DNS node associated with the CDN. The method also includes establishing address correlations between prefixed IPv6 network addresses and PQDNs that comprise indicators for at least a routing provider identifier and a cache node grouping. The method also includes receiving recursed DNS queries and responsively translating domain names in the recursed DNS queries into associated IPv6 network addresses to reach content indicated by the domain names, the associated IPv6 network addresses each determined by at least selecting one of the prefixed IPv6 network addresses according to a desired routing provider and a desired cache node grouping indicated in the PQDNs.

Claim (Index 11):
A method of operating a content delivery network (CDN) comprising a plurality of sites each having cache nodes that cache content for delivery to end user devices, the method comprising:\n establishing domain name relationships for use by a top-level domain name system (DNS) to resolve DNS queries to a DNS node associated with the CDN; in the DNS node, establishing address correlations between prefixed Internet Protocol version 6 (IPv6) network addresses and partially qualified domain names (PQDNs) that comprise indicators for at least a routing provider identifier and a cache node grouping; in the DNS node, receiving DNS queries and responsively translating domain names in the DNS queries into associated IPv6 network addresses to reach content indicated by the domain names, the associated IPv6 network addresses each determined by at least selecting one of the prefixed IPv6 network addresses according to a desired routing provider and a desired cache node grouping indicated in the PQDNs.
