IP addresses are often tied closely to a physical location. Anyone who knows your public IP address can make a very good guess as to where you are right now.
Depending on who you are, this can be either very convenient or very dangerous. Either way, most people want to be in control of who they reveal their location to and when, and don’t enjoy having their location revealed without their permission.
ExpressVPN lets you replace your IP address with a secure VPN IP address in any of 160 locations in 94 countries around the world, putting you back in control.
