# `geoip`

Match timezone, locale, geolocation and WebRTC IP to the proxy's exit IP.

**Use it for:** Any session behind a proxy in another country: timezone, locale and geolocation follow the exit IP, so the persona doesn't contradict its own address.

**Browsers:** [Camoufox](https://cdpfleet.com/docs/browsers/camoufox#opt-geoip).

## Details

-   **Type:** `boolean`
-   **Default:** true
-   **Example:** `{"geoip":false}`

At launch the browser looks up its public IP through your proxy and aligns its identity with that location. Set `false` to skip the lookup (faster start, but the location won't match the IP).

If the proxy can't reach the IP lookup services, the launch fails.
