Here you have an overview of all VT AIR **Address Resolution Protocol** and **Neighbor Discovery** entries.
The first is used for the internet protocol v4, the second for v6.

Each entry shows the IP **Address**, the used **Interface**, the **MAC** Address and its **State**, for example *STALE*, *DELAY*, *REACHABLE*, *FAILED*.

On the right side of the entries you have the possibility to delete the entry and remove it from the system.
