arping

Discover and probe hosts in a network using the ARP protocol. Useful for MAC address discovery.

• Ping a host by ARP request packets:

arping {{host_ip}}

• Ping a host on a specific interface:

arping -I {{interface}} {{host_ip}}

• Ping a host and stop at the first reply:

arping -f {{host_ip}}

• Ping a host a specific number of times:

arping -c {{count}} {{host_ip}}

• Broadcast ARP request packets to update neighbours' ARP caches:

arping -U {{ip_to_broadcast}}

• Detect duplicated IP addresses in the network by sending ARP requests with a 3 seconds timeout:

arping -D -w {{3}} {{ip_to_check}}
