This utility is provided to help network administrators to test their network, by using ARP cache poisoning, and generate ICMP packets to send over the LAN. The main idea is to allow administrators use this kind of software to secure their network to several known attacks.
This utility can also redirect switch based network traffic. It is possible to create a own made IP packet in which you can edit IP header or every ICMP field. Version 2.2 has memory leaks correction and better reliability.
