Re: show arp hardware type INCOMPLETE

That just means someone sent a packet to those IP addresses, the router
knows that if they exist, they are directly connected, so it should be able
to ARP for them. So it does, never gets a reply (hence the incomplete) and
purges them after givingup.

So its normal. To avoid it, you'd have to filter all traffic to address that
dont exist.
