Disclosed are systems, methods and computer program products for preemptive DNS resolution. A DNS proxy is provided for inspecting data packets transmitted to a client device on a first communication link. The proxy identifies one or more host device names embedded in the inspected data packets and resolves IP addresses associated with the embedded host device names. The proxy device transmits the inspected data packets to the client device without alterations on a second communication link. The second communication link has significantly higher propagation latency than the first communication link. The proxy then transmits to the client device, independent of the inspected data packets, the one or more host device names and the associated resolved IP addresses for use by the client device to establish connections to the host devices identified in the inspected data packet. |
