Anonymized network addressing in content delivery networks

A content delivery network (CDN) having a plurality of cache nodes that cache content for delivery to end user devices, the CDN comprising:

• an anonymization node comprising a processor, configured to establish anonymized network addresses for one or more of the cache nodes, for transfer of content to cache nodes from one or more origin servers that store the content before caching by the CDN, each anonymized network address configured to anonymize a type of content requested, and each anonymized network address configured to prevent an intervening network element from interfering with transmission of the content based on the type of content without needing to inspect the content;
• the anonymization node configured to provide one or more correlations between the anonymized network addresses and the cache nodes to a routing node of the CDN;
• the routing node configured to route the content transferred by the one or more origin servers responsive to content requests of the cache nodes based on indications of the correlations between the anonymous network addresses and the cache nodes.
