Abstract
System and method for distinguishing duplicate source address replies caused by interconnecting devices connected to a local area network and duplicate source address replies caused by non-interconnecting devices connected to the local area network. The present invention may be implemented through an analyzer. The method includes the following steps: In step 1, the present invention sends a first Address Resolution Request packet for a first Internet Protocol target address. In step 2, all Internet Protocol source address responses replying to the first Address Resolution Request packet are catalogued in a first reply set. In step 3, a second Address Resolution Request packet for a second Internet protocol target address is sent on to the network. In step 4, all Internet Protocol source address responses replying to said second Address Resolution Request packet are catalogued in a second reply set. In step 5, the first reply set is intersected with the second reply set resulting in an intersection set. In step 6, subtracting the first reply set from the intersection set to determine if there are any unique responders.
