There is no way to automatically determine the IP that is behind the proxy.
The client will have to send it manually in a data packet after it connects.
You can then compare it to the IP that the socket reports.  If they match,
then no proxy is being used.

The socket will report the public IP that it sees itself attached to.  That
is the IP that you always send data to.  The IP behind the proxy is not
directly accessible, nor should you be trying to send data to it directly
anyway when a proxy is present.  Always send to the proxy's IP.
