Internet network diagrams visualize the different devices within a network and how they obtain connection to the Internet. An Internet network diagram is a useful network diagnosis tool that helps you optimize your network and troubleshoot connectivity issues as they arise. A lot of details should be visible in your network infrastructure design, including:
1. A detailed network map.
2. The required cabling structure and arrangement.
3. The number, type, and location of all network devices.
4. Your IP addressing scheme.
5. Information about your network's security architecture and processes.
