how to identify non-host based devices:
1) check out mac-address ranges
Many of the small boxes will spoof the MAC address of the PC behind them.
They do this so that cable modem companies who track mac addresses don't
need to be called to tell them.
Of course you then have Linksys which makes both a NAT-box and LAN cards.
So the MAC ranges are likely intermixed. On Cisco's, you can easily program
any MAC address you want.
