       netdiscover - an active/passive arp reconnaissance tool.


       netdiscover  [-i device] [-r range | -p] [-s time] [-n node] [-c count]
       [-f] [-S]


       netdiscover  is  an  active/passive  arp  reconnaissance  tool,  mainly
       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.


       -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:, or

       -p     Enable passive mode. In passive mode, netdiscover does not  send
              anything, but does only sniff.

       -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.

       -n node
              Last ip octet of the source ip used for scanning. You can change
              it if the default host is already used.  (allowed  range:  2  to
              253, default 66)

       -S     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)

       -f     Enable fast mode scan. This will only scan for .1, .100 and .254
              on each network. This mode is usefull while searching for ranges
              being used.  After you found such range you can make a  specific
              range scan to find online boxes.


       If  passive  mode  (-p)  or  scan  range  (-r)  options  arent enabled,
       netdiscover will scan for common lan addresses.
