Network Recognisance Tool to allow for reconnaissance enabling users to passively or actively detect hosts on their network. The passive mode uses ARP traffic on a selected interface to detect IP and MAC address pairings. The Active mode sends ICMP requests to every host on the network and displays a list of addresses for which a reply was received.
