Strange traffic from proxmox to 239.192.153.78 on port 5404/5045.

Hi everyone, recently I noticed strange traffic from promxox nodes to 239.192.153.78:5405.
Digging, it seems cman's port for communication.
Now the question: why is cman sending this kind of traffic outside from the local network?
Proxomox server are on 192.168.10.0/24 subnet

Thanks

It's not a public IP (yes, seems so!), is a multicast one, have a look at
