Virtual private networks are designed to preserve online privacy by encrypting internet traffic and hiding IP addresses that can be used to determine user location. Most users are aware of this when they try to access a website or service when they are overseas. The IP address generally triggers the loading of a URL in the local area and may restrict access to a U.S. service or site. A VPN can be used to circumvent such restrictions and limitations. For example, a U.S. user traveling in Europe might be blocked from accessing paid streaming services that the user could access if he or she were physically located in the U.S. A VPN masks the local European IP address and can enable the person to view U.S.-based content.
A VPN server, then, replaces an IP address with its own as it passes the encrypted data to the public internet. For example, if you live in New York, your IP address will show that you are connecting from New York. However, if you connect to a VPN server based in Amsterdam, the IP address appears to indicate that the user is based in the Netherlands.
On the surface, VPNs seem to hide the digital footprint of a user. However, they are not a guarantee of complete anonymity. For example, ISPs are aware of when someone is using a VPN, but they can’t view specific online activity protected by a VPN, such as browsing history, DNS queries, downloaded files and personal data. However, VPNs are useful in preventing Big Brother — in the form of various government agencies — from snooping on users and where they visit online. The use of an encrypted VPN tunnel offers a large measure of protection against unwanted eyes.
