What Does a VPN Do?

An IP teoh VPN provides a secure connection between two devices over the internet. This protects data from being viewed by hackers, government or other people who shouldn’t have access to it. It also makes it more difficult for other users of the same Wi-Fi network to see your activity.

VPNs use different protocols to provide security. One of the most popular is OpenVPN, which is supported on many devices. Another is IPSec, which uses encryption to prevent traffic from being read by anyone else. IKEv2 is another common protocol that uses both IPSec and VPN to provide speed and security. It’s supported by many mobile devices, and it’s used with other protocols like PPTP to provide additional security.

Understanding VPNs: IP Through VPN

When you connect to a VPN, the traffic from your device goes through a series of relays. Each of these relays encrypts the information before sending it to the next relay. By the time it gets to the final relay, only the server can decode it. This means that if someone is spying on you, they’ll only be able to get your IP address, not any details about what you were doing online.

This is a great way to protect yourself from snoopers and cybercriminals. However, some other features can make a VPN even better. Some examples are split tunneling, which allows you to select which apps go through the VPN and which don’t. This is useful for businesses that want to prioritize important applications.
