 ## Manually defining your public IP
+
 In the `hosts` file we explicitly ask for your server's external IP address when defining `ansible_host`, because the same value is used for configuring Coturn.
+
 If you'd rather use a local IP for `ansible_host`, make sure to set up `matrix_coturn_turn_external_ip_address` replacing `YOUR_PUBLIC_IP` with the pubic IP used by the server.
 
 ```yaml
 matrix_coturn_turn_external_ip_address: "YOUR_PUBLIC_IP"
 ```
 
+If you'd like to rely on external IP address auto-detection (not recommended unless you need it), set `matrix_coturn_turn_external_ip_address` to an empty value. The playbook will automatically contact an [EchoIP](https://github.com/mpolden/echoip)-compatible service (`https://ifconfig.co/json` by default) to determine your server's IP address. This API endpoint is configurable via the `matrix_coturn_turn_external_ip_address_auto_detection_echoip_service_url` variable.
+
+If your server has multiple external IP addresses, the Coturn role offers a different variable for specifying them:
+
+```yaml
+# Note: matrix_coturn_turn_external_ip_addresses is different than matrix_coturn_turn_external_ip_address
+matrix_coturn_turn_external_ip_addresses: ['1.2.3.4', '4.5.6.7']
