    Thanks for the effort. I figured it out. I'm just beginning to understand this subnetting stuff. I was getting confused with it being a Class B network. The "magic number" here is '1'.

    172.18.179.0 = network ID
    172.18.179.1- 254 = Valid hosts
    172.18.179.255 = Broadcast Address.

    172.18.180.0 = next subnet. because of 255.255.255

    Correct.
    AND...if the mask would have been 255.255.255.128, you would have been in the 172.18.179.128 network.
    Because:
    Your subnets would have then been:
    172.18.179.0 containing the valid hosts 172.18.179.1 - 172.18.179.126 and your broadcast of 172.18.179.127
    AND
    172.18.179.128 containing the valid hosts 172.18.179.129 - 172.18.179.254 and your broadcast of 172.18.179.255

    If you need more help, just ask. Someone will help.

    You should use binary conversion method to understand easily. :)
