Abstract:
1. A computer-implemented method comprising: obtaining a first DNS query from a client computing device at a first DNS server, wherein the first DNS query corresponds to a first requested resource and wherein the first DNS server corresponds to a content delivery network service; obtaining a query IP address associated with the first DNS query at the first DNS server, wherein the query IP address is associated with the client computing device; responsive to obtaining the query IP address, obtaining, at the first DNS server, a location-based identifier at least based on a partial IP address corresponding to the query IP address from a routing data store, wherein the routing data store includes at least partial IP address to location-based identifier mappings, and wherein the location-based identifier corresponds to physical, logical, or relative location information associated with the client computing device; resolving the first DNS query based on the location-based identifier; collecting performance data associated with transmission of the first requested resource; modifying the routing data store based on the performance data with an updated location-based identifier associated with the query IP address; obtaining a second DNS query from the client computing device at a second DNS server, wherein the second DNS query corresponds to a second requested resource; resolving the second DNS query based on the updated location-based identifier associated with the query IP address associated with the client computing device.
