IT Infrastructure Network Diagram Examples

Network diagrams map IT infrastructure: servers, switches, routers, firewalls, and the connections between them — the reference document for architects, ops teams, and incident responders.

How to

How to use a network diagram template.

  1. 01List the nodes

    Name each device or service (router, switch, firewall, server, cloud service) — the AI uses appropriate network icons.

  2. 02Describe the connections

    Say which devices connect to which, and the link type (LAN, WAN, internet, VPN) — the AI draws labeled connections.

  3. 03Group into network zones

    Describe security zones (DMZ, internal, public internet) and the AI adds dashed-border groupings.

  4. 04Add IP addresses and VLANs (optional)

    Annotate nodes and links with IP ranges and VLAN IDs for the operational reference view.

FAQ

Questions about network diagram templates

What is a network diagram?

A diagram showing the physical or logical layout of a network — how devices connect, what security zones exist, and how traffic flows. Essential for infrastructure planning, incident response, and compliance documentation.

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

A physical diagram shows actual hardware and cable connections. A logical diagram shows IP addresses, VLANs, subnets, and routing — the logical topology regardless of physical location. Both are standard types in network documentation.

Can I diagram cloud infrastructure (AWS/Azure/GCP)?

Yes — describe your cloud services (VPC, subnets, load balancers, instances) and the AI builds a network diagram with cloud service icons and connection labels.
