Facing the local area network into hundred computers, one by one to detect is obviously not a good way. In fact, we just use the basic principle of ARP virus: To send fake ARP spoofing broadcast, poisoning the computer itself disguised as a gateway characteristics, can quickly lock poisoned computers. You can imagine using the program to achieve the following functions: When the network is normal, firmly remember the correct gateway IP address and MAC
