arping

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 received.

Stop after sending count ARP REQUEST packets. With deadline option, arping waits for count ARP REPLY packets, 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 alive.

Name of network device where to send ARP REQUEST packets. This option is required.

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 answered.
