This also means that we now only have 4 bits to use for the host address on each network. So this means the maximum number of host addresses on each subnet is 2^4 = 16.
Deliverables
Now that you understand how to make decisions regarding subnet masks, work on the following problems:
1. Given a Class C network and a number of subnets required, complete the table to identify the number of bits to borrow from the host field to use for the subnet field and the maximum number of host addresses available per subnet.
