Abstract
Some embodiments provide systems and methods for implementing discrete mapping for targeted caching in a carrier network. In some embodiments, discrete mapping is implemented using a method that caches content from a content provider to a caching server. The method modifies a DNS entry at a particular DNS server to resolve a request that identifies either a hostname or a domain for the content provider to an address of the caching server so that the requested content is passed from the cached content of the caching server and not the source content provider. In some embodiments, the particular DNS server is a recursive DNS server, a local DNS server of the carrier network, or a DNS server that is not authoritative for the hostname or domain of the content provider.
