    Have a small network with a single subnet connected to the internet.
    Router is the default gateway is has been assigned
    192.168.12.34/28

    I needed to figure out the following:
    IP Address
    Subnet Mask

    I figured out the Subnet mask of 255.255.255.240 from the CIDR 28 but I can't figure out how they came up with the IP.

    **Answer is 192.168.12.46
    Their explanation is with a 28bit mask, the router is on subnet 192.168.12.32, and valid addresses are 192.168.12.33 to 192.168.12.46. Can't use 192.168.12.32 because its the subnet address. Can't use 192.168.12.47 because its the broadcast address.
