What This Template Offers

A fully structured physical network diagram covering ISP connectivity, firewalls, switches, DMZ servers, internal LAN devices, wireless access, and endpoints — ready to adapt to your environment.

Use cases

Perfect Use Cases

IT Infrastructure Documentation

Keep an accurate record of every physical device and connection in your organization. Share with new team members or auditors instantly.

Network Security Review

Visualize firewall placement, DMZ boundaries, and internal segments to identify exposure risks and plan remediation.

Office or Data Center Planning

Plan cable runs, switch placements, and device layouts before deployment to avoid costly mistakes on-site.

Troubleshooting and Incident Response

Quickly trace the path from a failing device back through switches and routers to isolate the root cause of network issues.

Customize

How to Customize

Add or Rename Devices

Replace the placeholder node names with your real device names, hostnames, or IP addresses to match your actual infrastructure.

Adjust Network Segments

Add additional switches, VLANs, or server groups by inserting new nodes and drawing connections between them in the relationship editor.

Set the Root Node and Export

Choose your core router or main switch as the root node to center the layout, then download or embed the finished diagram for documentation or presentations.

Key Benefits

  • Saves hours compared to building a network diagram from scratch
  • Clear visual hierarchy makes complex topologies easy to understand at a glance
  • Works for networks of any size — small offices to enterprise data centers
  • No specialized diagramming software required — runs entirely in your browser

Pro Tips

  • Use the 'cloud' shape for external nodes like the ISP or third-party services to visually separate them from internal infrastructure.
  • Group servers by function (DMZ vs. internal) using separate switch nodes to make security boundaries immediately obvious.
  • Enable zoom and pan when presenting to stakeholders — it lets you drill down from the full topology to individual device details without switching views.
