grammar

arping(options)(parameters)

Options

-b: Used to send Ethernet broadcast frames (FFFFFFFFFFFF). arping uses the broadcast address initially and the unicast address after receiving the response.
-q: quiet output does not display any information;
-f: Indicates to exit after receiving the first response message;
-w timeout: Set a timeout in seconds. If the specified time is reached and arping has not fully received the response, it will exit;
-c count: Indicates that it will stop after sending the specified number of ARP request packets. If the deadline option is specified, arping will wait for the same number of arp response packets until timeout;
-s source: Set the value of the SPA field in the arp packet sent by arping. If it is empty, proceed as follows. If it is DAD mode (conflict address detection), it is set to 0.0.0.0. If it is Unsolicited ARP mode (Gratuitous ARP), it is set to the target address. Otherwise, it is derived from the routing table;
-I interface: Set the network interface used by ping.

Parameters

Destination host: Specify the destination host for sending ARP messages.
