Figure 5.1 – Homelab architecture

Here is a small explanation of each component in the figure:

• Lan: This is the local network that you are going to use. In our example, the network is defined as 192.168.0.0/24.
• Switch: A switch is also a network connecting device which connects various devices in the same network.
