Is there a filter to display only broadcasts?

Is there a filter to display only broadcasts, not just 255 destinations but all broadcast of any type?

Thank you

Hello Pauli

Broadcast messages happen on Layer 2 or Layer 3. Try this Wireshark display filter for Layer 2 broadcasts (which includes IP and other protocols, like ARP:

eth.dst.ig == 1

To focus on IP broadcast messages you might try

eth.dst.ig == 1 and ip

Good luck!

The display filter can be complex depending on your network because IPv6 uses multicast. Mis-configured static address can create problems too.
