When you experience IPs from the front-commerce hosting instead of getting the customer IP stored in the order, you need to ensure your Magento provider is not changing the value of the X-Forwarded-For header.

To easily ensure if this value is altered you can temporarily add the following PHP script to the Magento instance at pub/fc-test-ip.php with the following content

Then call it using curl

If you do not retrieve the IP passed in the X-Forwarded-For in the response, please contact your Magento provider to ensure this header and values pass through each proxy without being modified or removed
