    The network ID is the first IP address in a network, and the broadcast address is the last. The default gateway is what devices on that network are configured to be routed.
    CIRD IP Range (ID-Broadcast) Subnet Mask IP Quantity
    131.107.0.0/20 131.107.0.0 – 131.107.15.255 255.255.240.0 4096

    The network ID is 131.107.0.0

    The broadcast is 131.107.15.255

    Usable IP addresses for networking is 131.107.0.1-131.107.15.254

    Microsoft Note from: http://support.microsoft.com/kb/164015

    Incorrect Default Gateway: A computer configured with an incorrect default gateway will be able to communicate with hosts on its own network segment, but will fail to communicate with hosts on some or all remote networks. If a single physical network has more than one router, and the wrong router is configured as a default gateway, a host will be able to communicate with some remote networks, but not others. This problem is common if an organization has a router to an internal TCP/IP network and another router connected to the Internet.
