How retrieve Public IP?

[mttc]

I have Remoting App (on tcp channel with no web server). I need to
know the Client IP(public ip). I not find any way to retrieve this
info when client call remoting procedure (singelton)?
So my Q is how can client know his public IP to send it to server?

Your public IP is often assigned by your ISP--to which you likely have no
access.

There's various web-sites out there that will echo back your IP, for example
