# Track panelist IP and country
## View collected data
Private Panels automatically creates two panel properties **Registration IP** and **Registration Country** to track panelist origin. These properties are automatically updated during panelist sign-up, or when they first answer a screener. You can view a panelist's IP address and country by opening their profile then scrolling down to **Registration IP** and **Registration Country**.
To track IP for a Study Screener, follow [this guide](/private-panels/studies/duplicate-ip-protection.md).
The **Panel Panelists** page supports sorting and filtering for these panel properties.
These two panel properties can also be used to restrict your screener's availability in certain countries. More information about this can be found on our [Restrict availability by country](/private-panels/panel-management/restrict-availability-by-country.md) guide.
