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.

OPTIONS
-i device
The network interface to sniff and inject packets. If no interface is specified, first available will be used.
-r range
Scan a given range instead of auto scan. Valid range values area for example: 192.168.0.0/24, 192.168.0.0/16 or 192.168.0.0/8. Currently, acceptable ranges are /8, /16 and /24 only.
-l file
Scan ranges contained on the given file. It must contain only one range per line.
-p
Enable passive mode. In passive mode, netdiscover does not send anything, but does only sniff.
-m file
Scan a list of known MACs and host names.
-F filter
Customize pcap filter expression (default: "arp").
-s time
Sleep given time in milliseconds between each ARP request injection. (default 1)
-c count
Number of times to send each ARP request. Useful for networks with packet loss, so it will scan given times for each host. (default 1)
-n node
Last IP octet of the source IP used for scanning. You can change it if the default host (x.x.x.67) is already used. (allowed range is 2 to 253, default 67)
-d
Ignore configuration files at home dir (for autoscan and fast mode only). This will use default ranges and IPs for autoscan and fast mode. See below for information about configuration files.
-f
Enable fast mode scan. This will only scan for .1, .100 and .254 on each network. This mode is useful while searching for ranges being used. After you found such range you can make a specific range scan to find online boxes.
-P
Produces an output suitable to be redirected into a file or to be parsed by another program, instead of using interactive mode. Enabling this option, netdiscover will stop after scanning given ranges.
-L
Similar to -P but continue program execution to capture ARP packets passively after the active scan. phase to capture ARP packets passively.
-N
Do not print header. Only valid when -P or -L is enabled.
-S
(DEPRECATED) Enable sleep time suppression between each request. If set, netdiscover will sleep after having scanned 255 hosts instead of sleeping after each one. This mode was used in netdiscover 0.3 beta4 and before. Avoid this option in networks with packet loss, or in wireless networks with low signal level. (also called hardcore mode)
USAGE
If passive mode (-p), scan list (-l) or scan range (-r) options aren't enabled, netdiscover will scan for common LAN addresses (192.168.0.0/16, 172.16.0.0/12 and 10.0.0.0/8).
