What is a VPN?
How Do VPNs Work?
A virtual private network takes your internet connection and sends it through a private, secure tunnel. Just as your computer sends information through your network, the internet, and to a website, your computer can send information into a VPN.
A proper VPN will send information to a private system before it even touches the internet–often before it routes through the entire computer. This means no one–not your Internet Service Provider (ISP), neighbors, or spies can see easily.
What will people see when they try to spy on you or monitor your traffic. They will see information going through a VPN. Over a decade ago, that might have been a warning sign. Today, however, VPN use is common and even expected.
Once inside the VPN, your internet traffic will go wherever you send it. The only thing different is that you need to start and stop the VPN; once using a VPN, you browse the net just as normal.
Your traffic will have an all new IP address and other different network details. In higher quality VPNs, you can choose between various proxies–systems that represent your network–that will look like different states, provinces, regions, countries, and other areas.
