Just tested this with http://www.ExpressVPN.com http://www.ExpressVPN.com client on MacOS and it protected my IPv4 Public IP from being exposed but it does leak the local (NAT) IPv4 Private IP that I use on my internal network. Not good that it leaked anything but at least the public IP is hidden by their software.
