[CLUE-Tech] possible rogue IP solution?

[Dave Price]

Saw this on freshmeat ...

IP Sentinel 0.3
http://freshmeat.net/releases/104885/

   IP Sentinel is a tool that tries to prevent unauthorized usage of IP
    addresses within an ethernet broadcast domain by answering ARP
    requests. After receiving faked replies, requesting parties store
    the MAC in their ARP tables and will send future packets to this
    invalid MAC, rendering the IP unreachable.
