arping

Discover and probe hosts in a network using the ARP protocol. Useful for MAC addres 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 {{your_ip}}

  • Determine whether an IP address is already in use in the network by sending it ARP requests with a 3 seconds timeout:

arping -D -f -w {{3}} {{target_ip}}
