When you use a VPN, the IP address of the server you choose is supplied instead of yours. The VPN service then encrypts and relays that content to you, keeping your activity private.

In common, you’ll want to make sure the VPN you choose offers military-grade encryption, fast speeds, a large number of servers in various locations, and 24/7 customer support.

If your VPN’s kill switch is working correctly, your IP log shouldn’t show your actual IP address even when switching servers or during an unexpected internet disconnection.

However, using a VPN server that's far away can cause some connection problems. When you choose which location to set your VPN to, you're also choosing which server you're connecting to.
