Delegation of content delivery to a local service

A computer-implemented system comprising:

• A. a content provider server comprising circuitry forming at least one processor and a memory storing processor-executable codes, wherein the at least one processor is configured to:
• (i) send a delegation request to a provisioning system of an Internet Service Provider, the delegation request comprising an instruction to begin implementing delegation of a content associated with a particular domain name, the implementation of the delegation comprising overriding Domain Name System (DNS) answers associated with the particular domain name;
• B. the provisioning system configured to receive the delegation request and based thereon take an action, the action being any of:
• updating and flushing a cache that is associated with the provisioning system and from which at least one recursive DNS server managed by the Internet Service Provider retrieves DNS resolution results;
• C. the recursive Domain Name System (DNS) server managed by the Internet Service Provider comprising circuitry forming at least one processor and a memory storing processor-executable codes, wherein the at least one processor is configured to:
• (i) receive the delegation request from the provisioning system;
• (ii) receive a client Domain Name System (DNS) query to resolve the particular domain name to a network address;
• (iii) in response to the client DNS query, addressing the cache to look up and retrieve a cached resolution result, and resolve the particular domain name to a local content server managed by the Internet Service Provider, based on the cache resolution result.

A non-transitory processor-readable medium having instructions stored thereon, which when executed by one or more processors, cause the one or more processors to implement a method, comprising:

• A. with a provisioning system of an Internet Service Provider, receiving a delegation request from a content provider server, the delegation request comprising an instruction to begin implementing delegation of delivery of content associated with a particular domain name, the implementation of the delegation comprising overriding Domain Name System (DNS) answers associated with the particular domain name;
• B. with the provisioning system, receiving the delegation request and based thereon taking an action, the action being any of:
• updating and flushing a cache that is associated with the provisioning system and from which at least one recursive DNS server managed by the Internet Service Provider retrieves DNS resolution results;
• C. with the at least one recursive DNS server managed by the Internet Service Provider:
• (i) receiving a client Domain Name System (DNS) query to resolve the particular domain name to a network address;
• (ii) in response to the client DNS query, addressing the cache to look up and retrieve a cached resolution result, and resolving the particular domain name to a local content server managed by the Internet Service Provider, based on the cached resolution result.
