arping: Ping a host and stop at the first reply.

arping

$ arping -f ${host_ip}

try on your machine

The command "arping -f ${host_ip}" is used to send ARP (Address Resolution Protocol) requests to a specified IP address in a network.

Here is a breakdown of the command:

"arping" is the command itself. It is a utility that sends ARP request/reply packets to determine whether a specific IP address is being used by any device on the network.
"-f" is an option or flag used with the arping command. It stands for "force" and instructs arping to send ARP requests even if the IP address is already in the ARP cache.
"${host_ip}" is a variable or placeholder that should be replaced with the actual IP address you want to target. The IP address can be either IPv4 or IPv6.

When the command is executed with a specific IP address, arping will send an ARP request to that address, and the target device with that IP address will respond with an ARP reply if it is active on the network. This command is often used for network troubleshooting or checking the availability of a specific IP address.
