      IP Sentinel, Local Network Watch Guard
    ------------------------------------------------------------------------

    DETAILS

    IP Sentinel is a tool that prevents 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.

    ADDITIONAL INFORMATION

    The tool can be downloaded by going to:
