Your company has just purchased a lease on the 205.3.3.0 Class C public IP address range, which means that your company can assign the IP addresses from 205.3.3.0 to 205.3.3.255.

You need to subnet this Class C address range to provide separate VLAN subnets for each of the following departments:

I.T. Department needs 28 addressesAccounting Department needs 23 addressesExecutive Office needs 5 addressesSales Department needs 90 addressesMarketing Department needs 26 addressesSerial link A needs 2 addressesSerial link B needs 2 addresses Using VLSM (Variable Length Subnet Masking), partition your available Class C address space to accommodate the above requirements. Answer the below questions to explain your solution:

1. List your requirements from large to small, and designate what block size will be needed to accommodate each department's requirements:

2. Using these required block sizes, list the IP address subnet names for each department.  Remember in every table, use the same department listing of large to small as you did above in question (1).(Hint: First subnet name is 205.3.3.0)

3. List the broadcast addresses for each subnet:

 4. List the available host addresses for each department's subnet:

5. Given the block sizes used, list the Subnet Mask needed for every device on each subnet:

6. Extra Credit: 

a. What is the remaining block size (i.e., how many IP addresses are left after all of the above blocks are assigned)?

b. What subnet mask could be used for the remainder block?
