    Hi,

    Could you run a packet sniffer (like Etheral), and log the traffic for
    the specific IP's in question? You would see when the MAC address
    changed for a given IP.

    Once you knew their MAC address, you could log all their traffic. Maybe
    block their traffic. Ban them from your network.

    thx!
