Often you can ping the broadcast address and the duplicate IP addresses will show up in the reply.
There's absolutely nothing on my network that answers a ping broadcast -- perhaps because of the wireless bridge -- and increasingly many things these days never bother answering ping at all.
Engineers seem to be forgetting why ICMP exists. I don't like it, but if the equipment isn't my own, I have to live with it.
Equipment can't block or ignore ARP and still function on a local network though, so I've got the
arping tool installed standard everywhere. That's how I tracked down the dup.
arping2 -d -i lan 192.168.6.101 Note that without the -d, it won't show dups.
