Abstract
An authoritative domain name system server includes a memory configured to store a set of instructions, and a processor configured to execute the set of instructions. The processor obtains a first Internet Protocol address of a client system associated with a request for a domain name, and assigns a location of the authoritative domain name system server as an ingress region. The processor assigns the egress override as an egress region when the first Internet Protocol address matches the prefix of the egress override, otherwise obtains an egress table, determines a longest prefix match of the first Internet Protocol address, obtains a distance matrix for distances from the ingress location to a plurality of egress regions, and selects the egress region based on the distance matrix and the longest prefix match in the egress table. The processor selects a content node based on the one egress region, and assigns a second Internet Protocol address for the content node to a local domain name system server associated with the client system.
