# IP Filtering

IP filtering allows you to restrict access to Hummingbird by specifying allowed IP addresses or ranges. This ensures that only users connecting from trusted networks are able to access your Hummingbird organization.

## Setting up IP filtering

Any admin user can configure IP filtering through the organization settings in the Hummingbird app.

1. Navigate to **Organization Settings** and locate the [IP Filters section](https://app.hummingbird.co/settings/organization-settings/security-ip-filters).
2. Click **"Add IP Address or CIDR Range"** to create a new allowlist entry.
3. Enter an individual IP address or a [CIDR range](https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing), and click "Save."
4. Click "Add IP Address or CDR Range" again to add multiple entries to your allowlist.

## Important notes

* **Default behavior**: If no IP addresses or ranges are added, all traffic is allowed regardless of originating IP.
* **Access protection**: The system will verify your current IP address when saving to ensure you don't lock yourself out.
* **Environment separation**: Settings for IP filters are not shared between your Sandbox and Production environments.
* **Best practice**: Test any changes in your Sandbox environment before applying to Production.

## Troubleshooting

If you accidentally lock yourself out of Hummingbird, contact your Customer Success Manager or [Customer Support](mailto:support@hummingbird.co), who can modify the filter settings and restore your access.
