Lab Procedure 1. Consider the network shown below 1841 1841 Routero Router1 PC-PT PC-PT PCO PC1 2. Choose a private IP block and assign a suitable IP address to every PC/interface in the above diagram. Write the IP addresses in the figure above. Add a photo of the network after you write down the IP addresses to it. 3. Build the network shown in step 1. 4. Configure the IP address of the first computer with IP address and gateway as per your chosen IP addresses in step 2.

Suppose that you have a home network which includes a single router with WiFi and Ethernet capabil- ities. You have 15 devices connected to the router, 12 using WiFi and 3 connected through Ethernet. Give a diagram of these devices and identify how each device obtains an IP address. Also, describe how NAT is used when any of these devices request information from sources outside of the local area network.
