"Whenever any device connects to the internet - whether it's a laptop, a phone or a smart Lego brick - it's assigned a unique IP address that other devices can use to identify it. Think of the name you give the barista at a coffee shop, except instead of a hot beverage, you're being served websites and digital audio and video. That's the upside. The downside is that a device's IP address can be used to find its location in the real world."
"A VPN gets around that downside by running all your online activity through a middleman server before sending it to its destination. Instead of your real IP address, everyone sees the address of the VPN server, along with its geolocation. That means you can subvert any local restrictions getting in your way: You're actually in Houston, but so far as the website you're viewing is concerned, you seem to be coming from Amsterdam. Here's how to do it."
Every internet-connected device receives a unique IP address that can reveal its physical location and enable location-based services and restrictions. Service providers use IP geolocation for local content, targeted ads, and regional censorship. A VPN routes all traffic through an intermediary server, replacing the device's visible IP with the server's IP and geolocation. That masks the user's true location and can bypass geographic restrictions on streaming, websites, and censored information. Changing virtual location requires installing a reputable VPN app and connecting to a server in the desired country. The VPN server's IP becomes the apparent origin of the user's traffic.
