pip install netbox-ipcalculator

Common errors

error No module named 'netbox_ipcalculator' ↓

cause The plugin is not installed or not in the Python environment where NetBox runs.

fix

Run 'pip install netbox-ipcalculator' in the same environment as NetBox.

error Plugin 'netbox_ipcalculator' not found in PLUGINS ↓

cause Missing or incorrect entry in configuration.py.

fix

Add 'netbox_ipcalculator' (string) to the PLUGINS list in your NetBox configuration.py file.

error Invalid response from server (NetBox version mismatch) ↓

cause Plugin version is not compatible with the installed NetBox version, typically when NetBox is below 4.0 with plugin >=1.4.0.

fix

Either upgrade NetBox to 4.0+ or downgrade the plugin to an older version (<1.4.0).

Warnings

breaking Version 1.4.0 requires NetBox 4.0+. Upgrading from earlier versions without upgrading NetBox first will break the plugin. ↓

fix Ensure NetBox is at least version 4.0 before upgrading the plugin to 1.4.0+.

deprecated The old base URL 'plugins/ipcalculator/' was changed to 'plugins/netbox_ipcalculator/' in version 1.4.3. Direct links may break. ↓

fix Update any bookmarks or integrations to use the new URL path 'plugins/netbox_ipcalculator/'.

gotcha In disconnected environments, the plugin loads jQuery from a CDN by default. Version 1.4.8 fixed this by bundling a local copy. ↓

fix Upgrade to version 1.4.8 or later to avoid jQuery loading failures in offline NetBox installations.
