The drawing

What a network diagram is.

A network diagram shows the devices and connections in a computer network. It makes the path from the internet or WAN through security, routing, switching and endpoints visible at a glance.

It can also show the boundary between sites, VLANs or subnets. Labels for device roles, link types and management connections give the drawing the context needed for design and operations.

FAQ

Common questions

What is a network diagram?

A network diagram is a visual representation of network structure. It shows how routers, firewalls, switches, servers, wireless access points and client devices connect.

What should I include in a network diagram?

Include the sites, devices, links and major boundaries that matter to the reader. Add VLANs, subnets, link speeds, device names and management paths when they are relevant to the design.

What is the difference between a logical and physical network diagram?

A logical diagram focuses on roles and connectivity, such as VLANs, routing and security zones. A physical diagram shows actual equipment, ports, racks and cable paths.

Do I need networking expertise to make a network diagram?

Basic knowledge of the devices and their connections helps. You can begin with a plain-language description, then add the detail a technician or engineer needs.

Can I export a network diagram?

Yes. Export it as SVG, PNG or PDF for documentation, an operations runbook or a design review.
