Le planificateur privilégie les plages privées RFC1918. Vérifiez toujours les réseaux déjà utilisés par les VPN, sites distants, équipements opérateurs et réseaux invités avant de choisir un nouveau sous-network.
Use the result with confidence
Recommended workflow
- Use a non-sensitive representative input for VLAN planning.
- Run the operation and review the result before copying or exporting it.
- Validate the output in the target application or environment before relying on it.
What to verify
- Confirm the scope, units and input values before interpreting the output.
- Separate the observed result from the operational decision that follows from it.
- Validate the conclusion against the real target system, logs or configuration before changing production.
Questions about this tool
What should be documented when using VLAN planning?
Record names, identifiers, owners, addressing or flow direction and the technical dependency that makes each entry necessary.
How do I keep the result useful over time?
Use a clear source of truth, date changes and reconcile the document with real configuration during reviews.
What should I validate before production changes?
Compare the plan with routing, switching, firewall, DNS/DHCP and monitoring configuration that already exists.
