Importing Subnets

Import subnets into LightMesh to organise network segmentation. Supported fields include subnet (CIDR), zone, name, description, VLAN, default gateway, private network, region, status, and custom attributes.

Permission required: Imports require an app role of Owner, Administrator, or Contributor. See Roles & RBAC for details.

Required fields

• Subnet (required) — CIDR notation such as 10.0.0.0/17, or an address with a separate CIDR Mask column
• Zone — optional; blank imports into the Default zone
• Matching for updates: Subnet + Zone

How to import

Use the shared Import a spreadsheet guide for the current Imports wizard (Configuration > Imports → + New Import): choose type, upload the file, map columns, validate, and publish.

Templates for this type are linked from the Upload file step after you select it in the wizard.
