Assume that you have been assigned the 192.168.1.0/24 network. You need to create 6 subnets.

a. How many bits do you need to borrow from the host field for the subnet field?

We need to borrow 3 bits: 1 bit would give us 2 subnets, 2 would give us 4, and 3 would give us 8.

b. What is the maximum number of subnets that can be created with this number of bits?

We can create 2

3 = 8 subnets.

c. How many bits can be used to create the host space?

Each byte has 8 bits—we are using 3 bits to define the subnets, and this leaves us with 5 bits for the

host space.

d. What is the maximum number of host addresses available per subnet?

2

5 − 2 = 32 − 2 = 30. We have 5 bits for the host space, and each bit can assume a value of 1 or 0 (2

5

). However, two addresses on each subnet are reserved—the first one (all zeros) for the subnet address

and last address (all ones) for the broadcast address.

e. What prefix would you use? What is the subnet mask, in binary and decimal format?
