NAME
       arping - send ARP REQUEST to a neighbour host

SYNOPSIS
       arping [-AbDfhqUV] [-c count] [-w deadline] [-i interval] [-s source]
              [-I interface] {destination}

DESCRIPTION
       Ping destination on device interface by ARP packets, using source
       address source.

OPTIONS
       -A
           The same as -U, but ARP REPLY packets used instead of ARP REQUEST.

       -b
           Send only MAC level broadcasts. Normally arping starts from sending
           broadcast, and switch to unicast after reply received.

       -c count
           Stop after sending count ARP REQUEST packets. With deadline option,
           instead wait for count ARP REPLY packets, or until the timeout
           expires.

       -D
           Duplicate address detection mode (DAD). See RFC2131, 4.4.1. Returns
           0, if DAD succeeded i.e. no replies are received.

       -f
           Finish after the first reply confirming that target is alive.

       -I interface
           Name of network device where to send ARP REQUEST packets.

       -h
           Print help page and exit.

       -q
           Quiet output. Nothing is displayed.

       -s source
           IP source address to use in ARP packets. If this option is absent,
           source address is:

               o In DAD mode (with option -D) set to 0.0.0.0.

               o In Unsolicited ARP mode (with options -U or -A) set to
               destination.

               o Otherwise, it is calculated from routing tables.

       -U
           Unsolicited ARP mode to update neighbours' ARP caches. No replies
           are expected.

       -V
           Print version of the program and exit.

       -w deadline
           Specify a timeout, in seconds, before arping exits regardless of
           how many packets have been sent or received. In this case arping
           does not stop after count packet are sent, it waits either for
           deadline expire or until count probes are answered.

       -i interval
           Specify an interval, in seconds, between packets.

SECURITY
       arping requires CAP_NET_RAW capability to be executed. It is not
       recommended to be used as set-uid root, because it allows user to
       modify ARP caches of neighbour hosts.

AVAILABILITY
       arping is part of iputils package.
