Question 3

The network topology given in Figure Q3 has the network address of 200.20.20.0/24.

Apply an IPv4 addressing scheme using Variable Length Subnet Mask (VLSM) to the network. Your scheme should conserve as many IP addresses as possible. You are to use the next available subnet to subnet further. Illustrate your scheme by completing the following tasks.

(a) Assign appropriate subnet addresses to all the Local Area Networks (LANs) and Wide Area Networks (WANs).

Use the format given in Table Q3 to tabulate your workings for Q3(a). The table shows a sample entry.

(b) Derive the entire range of useable host IP addresses for all the LANs. Show your working.
