Discovered "ghost" devices

I am getting three devices "discovered" but they are not for anything real.  It simply finds the IP address, but then of course cannot detect anything by Agent or SNMP as they are not really devices.  There is nothing on these addresses and they do not show up in any ARP tables or respond to ping.  Looked through the logs, but they are not really showing anything. 

What I am looking for is how these devices are being discovered.  I suspect some device on my network is wrongly making a reference to them and this is getting picked up on during examination of routing / arp tables.  But that is a guess.

hi,

recently i have moved to run a network which someone else built and netxms found a bunch of nodes and their ip's but no ping could ever made.
after checking i found something called "live link" which is a feature of broadcom smart suite and it can be configured when creating teaming.
maybe this happened to you too

Yeah, I suspect something like that.  We do have some bonded interfaces, but that is not where they are in our case.  Have searched arp, routing, hosts, ... on MANY devices and not coming up with anything yet. 

Just a bit embarassed that I cannot track it down, but the software keeps detecting it.  If I delete them they get discovered again, so it was not some sort of one time fluke.  Also, always these three out of hundreds of devices on many subnets.  I will keep hunting...
