In the absence of a managed switch approach, you can issue "arp -n"
across the cluster nodes to see Mac/IP/Port bindings in the most recent
ARP cache.

A long-term solution to this was discussed on the list a year or so ago.
 The approach was to use arpwatch to automate IPs discovered on the
network into corresponding VM configs as comments, such as
 "#IP used by this VM recently: XXX.XXX.XXX.XXX[, YYY.YYY.YYY.YYY]*."
As a comment in the VM config, it shows up in the Proxmox GUI.
