Netdiscover 0.3-beta6 [Active/passive arp reconnaissance tool]
Written by: Jaime Penalba <jpenalbae@gmail.com>

Usage: netdiscover [-i device] [-r range | -p] [-s time] [-n node] [-c count] [-f] [-S]
  -i device: your network device
  -r range: scan a given range instead of auto scan. 192.168.6.0/24,/16,/8
  -p passive mode do not send anything, only sniff
  -s time: time to sleep between each arp request (miliseconds)
  -c count: number of times to send each arp reques (for nets with packet loss)
  -n node: last ip octet used for scanning (from 2 to 253)
  -S enable sleep time supression betwen each request (hardcore mode)
  -f enable fastmode scan, saves a lot of time, recommended for auto

If -p or -r arent enabled, netdiscover will scan for common lan addresses
