    Its not a network is it? Its just a loopback address for diagnosing network problems IIRC.

    It is a network, but it has been dedicated to the local host loopback address. try pinging 127.17.92.137 (or whatever address you like in the 127 range) and it will be the local host.
    That's 16 milion addresses down the drain....

    When IPv4 was dreamt up they thought it would be impossible to use all the addresses, they probably weren't too worried about loosing the 127 range.
