Where this is happening? LAN?
 Yes, it is LAN.

The IP who is requesting the arp's is know by you?
 Yes, it is one of the clients of that LAN.

What can be happing is a machine that is trying to flood the MAC table
of the local switch and making the switch work like a HUB, then the
attacker can sniffer the network and get the information that they want.

 Maybe, but I am concerned with the presence of target MAC in the who-has
packets.
