    The class of the network is designated by the subnet mask.

    your subnet mask is
    in binary this is 11111111.1111111.1111111.11100000

    This means the first 27 bits of your IP address designate the network you are on and the last 5 bits designate the machine number on the network.

    Therefore you have 5 bits which allows you 2^5 possible addresses on the network allowing you 32 possible ip addresses.

    here is a link to an explanation on subnets

    Hope that helps.
