arping: Broadcast ARP request packets to update neighbours' ARP caches.
$ arping -U ${ip_to_broadcast}
try on your machine

The command arping -U ${ip_to_broadcast} is used to send an Address Resolution Protocol (ARP) request as a broadcast message to a specific IP address.

Here is a breakdown of the command:

  • arping: This is the main command that is used to send ARP requests.
  • -U: This is an option used to specify that the ARP request is sent as a broadcast message. Broadcasting allows the request to be sent to all devices within the network, rather than to a specific device.
  • ${ip_to_broadcast}: This is a placeholder for the specific IP address to which the ARP request should be sent. You would need to replace ${ip_to_broadcast} with the actual IP address you want to target.

By using this command, you can send an ARP request to a specific IP address, which will then be broadcasted to all devices within the network. The purpose of the ARP request is to ask which device within the network has the given IP address.
