Abstract
A method, system, apparatus, and computer-readable memory containing instructions include receiving, at an agent operating on a client device, a (domain name system) DNS resolution request for a domain name. The DNS resolution request is transmitted to a first DNS server including a firewall service and a second DNS server within a local network to the client device. Responses to the DNS resolution request from the first and second DNS server are received. The agent determines how to resolve the DNS resolution request based on one or more of the received responses.
