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 1):
A method of operating a domain name system (DNS) node in a content delivery network (CDN), the method comprising:\n establishing address correlations between prefixed Internet Protocol version 6 (IPv6) network addresses and partially qualified domain names (PQDNs), wherein each PQDN comprises indicators for a routing provider identifier and a cache node grouping; receiving recursed DNS queries; for each of the recursed DNS queries, selecting one of the prefixed IPv6 network addresses according to a desired routing provider and a desired cache node grouping indicated in the PQDN in a given DNS query; replying to the given DNS query with the one of the prefixed IPv6 network addresses.
