# Client Public IP Detection

The Theme settings described below apply to Parallels Client for all supported platforms.

When configured, a Parallels client will use the selected service to retrieve the endpoint’s public IP and send it to the Parallels RAS Connection Broker along with other connection information. The received endpoint’s public IP is stored in the Parallels RAS variable %CLIENTPUBLICIP%, which can be configured as attribute values sent to a RADIUS provider.

The following settings can be configured:

* **Do not use client public IP detection:** The client’s public IP will not be captured and sent to Parallels RAS Connection Broker.
* **Use Parallels client public IP detection service:** The client’s public IP is captured using a Parallels-managed public IP detection service (<https://whatismyip.parallels.com/v1>) and sent to Parallels RAS Connection Broker.\
  \
  Use the test button to test the Parallels-managed public IP detection service.\
  \
  The public IP of the machine that runs the Parallels RAS console should be returned. Clients need to be able to access the Parallels-managed public IP detection service via HTTPS.
* **Use Custom client public IP detection service:** The client’s public IP is captured using a custom public IP detection service that can be specified as the service URL.\
  \
  Use the test button to test the specified public IP detection service.\
  \
  The public IP of the machine that runs the Parallels RAS console should be returned. Clients need to be able to access the specified public IP detection service via HTTPS. The custom service must return a JSON response containing the public IP in one of the following fields: "ip", "IP", "ipString", or "ipAddress".\
  \
  Example JSON response:\
  \
  {\
  &#x20;   "ip": "84.104.46.194"\
  }
