ARPing
##################

You can find the ARPing Tool at **Tools → ARPing**.

The information is shown in real time in your browser.

With this tool you can test the reachability of a host via a MAC address.
It will send an arp message from this system to the entire L2 and will get an answer if the MAC address is reachable.

Enter the MAC address of the destination and click on **ARPing** to start.
You can specify the **number of pings** and which **source** interface shall be used, which uses auto by default.
