List the address space that is still available for future expansion.
There is only on subnet left: .252/30.
Exercise 3
Your address space is 192.168.6.0/23. The number of hosts needed for each LAN is shown in Figure
6-5. Use VLSM to create a contiguous IP addressing scheme. Label Figure 6-5 with your addressing
scheme. Don't forget the WAN links.

List the address space that is still available for future expansion.
For the solution shown in Figure 6-5, the address space still available is .7.108/30, .7.112/28, and
.7.128/25.
Exercise 4
Your address space is 10.10.96.0/21. The number of hosts needed for each LAN is shown in Figure 6-
6. Use VLSM to create a contiguous IP addressing scheme. Label Figure 6-6 with your addressing
scheme. Don't forget the WAN links.
