Abstract
Systems, methods, apparatuses, and software for an edge network that serves content 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 edge network. 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 server 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 server node grouping indicated in the PQDNs.
