So I guess the strange IP address probably comes from some Lite-On device somewhere in my house - maybe on the server itself, an HP MicroServer. There are so many possible electronic culprits today.
You should be able to use nmap to scan the device.
Thanks very much for the suggestion, I'll try that.
I've been surprised how much information I get from iptraf-ng, which I only discovered recently. I knew about "arp -a", but I'm told I should be using "ip neigh". However, that doesn't give the name of each device on the network (if known), as arp does.
