Thanks for the reply Joan,
I was looking specifically to filter gratuitous ARPs only, i.e. ones where the target IP address of the ARP is the same as the sender IP address of the ARP {also for all host IP addresses not a specific host IP address)

Hi MTIA,

Try this display filter:
(arp.src.proto_ipv4 == 192.168.1.111) && (arp.dst.hw_mac == 00:00:00:00:00:00)

It displays gratuitous arp requests and just a few other arp requests.

Hope this helps,
Joan

Any suggestions how I can achieve this?
