    My PC is connected to the Net via cable and there are no other PCs

    I left my PC to do some P2P downloading. When I got back Zone Alarm
    said it had detect a new Private Network with an IP address of

    The screen had frozen and I had to do a reboot. On rebboting Zone
    Alarm didn't ask about again.

    WHOIS tells me nothing about Does anyone know what IP
    address it is?

    Pasted from: http://www.howtonetworking.com/ipconfig.htm#Why

    Symptom: The Internet Assigned Numbers Authority (IANA) has reserved for Automatic Private IP Addressing. If the
    computer can't get ip from DHCP, APIPA provides an address that is
    guaranteed not to conflict with routable addresses.

  3. This means that your PC lost its internet connection, and was unable
    to get an IP address. Any 169.x.x.x address is only assigned when all
    else fails and your Pc can't find your ISPs server.

    From ZA's point of view, its completely harmless. From your point of
    view, it means your internet connection fell over. You may want to
    explore why.

  4. This is a non routable IP address similar to 10.x.x.x and 172.16-172.31 and
    192.168.x.x. Windows will also default to it if it can not get an IP
