arping - send ARP REQUEST to a neighbour host
arping [-AbDfhqUV] [-c count]
[-w deadline] [-s source]
[-I interface] destination
Ping destination on device interface by ARP packets, using source
The same as -U, but ARP REPLY packets used instead
of ARP REQUEST.
Send only MAC level broadcasts. Normally arping
starts from sending broadcast, and switch to unicast after reply
Stop after sending count ARP REQUEST packets. With
deadline option, instead wait for count ARP REPLY packets, or
until the timeout expires.
Duplicate address detection mode (DAD). See RFC2131,
4.4.1. Returns 0, if DAD succeeded i.e. no replies are received
Finish after the first reply confirming that target is
Name of network device where to send ARP REQUEST
Print help page and exit.
Quiet output. Nothing is displayed.
IP source address to use in ARP packets. If this option
is absent, source address is:
In DAD mode (with option -D) set to 0.0.0.0.
In Unsolicited ARP mode (with options -U or
-A) set to destination.
Otherwise, it is calculated from routing tables.
Unsolicited ARP mode to update neighbours' ARP caches. No
replies are expected.
Print version of the program and exit.
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

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.
arping is part of iputils package.
