Abstract
A method and system for domain name resolution in a communications network including the steps of intercepting communication to and from the network and replacing DNS primary and DNS secondary IP address by an interceptor program. The interceptor program copies then replaces the IP addresses in messages received from the network to a spoof address so that an alternate application will receive the domain name resolution requests. The interceptor program replaces the IP addresses in messages sent to the network from the spoof address to the copied addresses. The alternate application receives the domain name resolution request and replaces the IP address of the request which is the spoof address to the copied IP addresses. The alternate application sends the domain name resolution requests to the copied IP addresses operatively simultaneously.
