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.
My HP Microserver N40L (the original version), the NIC is Broadcom,
02:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5723 Gigabit Ethernet PCIe (rev 10)
and its MAC is A0:B3:CC:xx:xx:xx
I have the same Broadcom controller in my MicroServer, but there is a second Intel 82574L ethernet controller in the machine, which could conceivably be the culprit.
What I don't really understand is why the dhcpd server on my CentOS machine does not give this device a proper address. (There are lots of spare 192.168.2.* slots.)
As far as I can see from iptraf-ng, no packets are currently coming or going from this 169.254.* address, which I see from google is a "link-local" address.
