What is my IP address using ExpressVPN?

It's not possible to know the specific IP address used when employing ExpressVPN or any VPN service without direct access to the connection details. When using ExpressVPN, the IP address is masked and changed to one provided by the VPN server. This new IP is shared among multiple users for privacy reasons and depends on the server location selected within the ExpressVPN application. Thus, to determine the IP address provided by ExpressVPN, one would need to check the VPN client status or use an online service to display their current public IP address after establishing a VPN connection.
