Your company is given the block of addresses at 154.16.128.0/17. You must create 256 subnets with equal number of hosts in each subnet. In solving this problem, you must answer the following questions.

1.Write out the binary equivalent of 154.16.128.0

2.Calculate the number of subnet bits needed

3.Draw a vertical line between where the subnet bits end and the host bits start on the binary equivalent you created in step 1.

4. Write out the Subnet Mask below in binary

5. Convert the binary in step 4 to dotted decimal. This is your Subnet Mask

6. How may host bits do you have? _____

7. 2^{number of host bits} = _____ -2 = ______________

8. Why are you subtracting two in the formula of question 7?

9. For the First Subnet what is

-subnet ID _______________

-first host ________________

-last host ____________ ____

-broadcast _______________

10. For the Last subnet what is

-subnet ID ______________

-first host _______________

-last host _______________

-broadcast ______________
