netdiscover [-i device] [-r range | -l file | -p] [-s time] [-n node] [-c count] [-f] [-d] [-S] [-P] [-L]
netdiscover is an active/passive arp reconnaissance tool, initially developed to gain information about wireless networks without dhcp servers in wardriving scenarios. It can also be used on switched networks. Built on top of libnet and libpcap, it can passively detect online hosts or search for them by sending arp requests.
Furthermore, it can be used to inspect your network's arp traffic, or find network addresses using auto scan mode, which will scan for common local networks.
If passive mode (-p), scan list (-l) or scan range (-r) options arent enabled, netdiscover will scan for common lan addresses.
