In one example, an edge server including a processor, memory, and a domain name system (DNS) edge application stored in the memory and executed by the processor is provided. The DNS edge application is configured to: receive a first DNS query requesting a first DNS record; forward the first DNS query to an origin server; receive a response to the first DNS query from the origin server; store the response on the edge server; receive a second DNS query requesting a second DNS record; determine that the second DNS record is not stored on the edge server; and generate a new response to the second DNS query based on the stored response. The first DNS query and the second DNS query may be the same DNS query, and the second DNS query is not forwarded to the origin server.
