Network & IP Tool
VLAN Planner
Create a practical VLAN plan with IDs, names, subnet mappings, purpose and operational notes.
Quick Answer
Document VLAN IDs, subnets and operational purpose before configuring switches or firewalls.
Add VLANs, assign subnet ranges, describe their purpose and check for duplicate VLAN IDs before exporting the plan.
Method
What the planner helps with
VLAN planning is mostly documentation discipline: define the ID, name, subnet, purpose and operational notes before implementation. This helps avoid duplicate IDs, unclear naming and poor handover records.
Inputs
Recommended fields
Use VLAN ID, name, subnet, purpose and notes to keep implementation and handover documentation aligned.
Uses
Where this helps
Useful for switch rollouts, firewall planning, routing documentation, guest networks, voice networks, management networks and operational handover.
FAQ
VLAN notes
What is the normal VLAN ID range?
Standard VLAN IDs use the range 1 to 4094. Some platforms reserve specific IDs for internal or default use.
Should every VLAN have a subnet?
Usually yes for routed IP networks. Some Layer 2-only or special-purpose VLANs may not have a directly assigned subnet.
Why check duplicate IDs?
Duplicate VLAN IDs with different purposes can cause documentation errors, configuration mistakes and operational confusion.

Disclaimer
Planning reference only
This planner supports documentation and planning only. VLAN design should be checked against network architecture, security policy, switch platform capabilities and operational standards before production deployment.
Workflow
Need quick VLAN planning guidance?
Use this planner to prepare VLAN IDs, subnet assignments and purpose notes before switch configuration, firewall rule creation or handover documentation.
