Host enumeration is the act of determining the IP address of potential targets on a network. Icmpenum uses not only ICMP Echo packets to probe networks, but also ICMP Timestamp and ICMP Information packets as well. Furthermore, it supports spoofing and promiscuous listening for reply packets. Icmpenum is great for enumerating networks who block ICMP Echo packets but have failed to block Timestamp or Information packet, or for upstream sniffing of trusted addresses.

This is a proof-of-concept tool to demonstrate possible distributed attacking concepts, such as sending packets from one workstation and sniffing the reply packets on another.
