If you are not yet familiar with the term VPN (Virtual Private Network), we warn you that it is a tool that will completely change the way you browse and protect yourself on the Internet.  Basically, a VPN stands as a method that is used to connect you to the Internet privately, with the aim that the system can optimally hide your real IP address. For this, both the traffic you make on the Internet and your data are routed through the use of a private and encrypted tunnel in a completely secure way through networks that are effectively public.

VPN connections are not a recent invention, but their use has proliferated today. Previously, it was used in a business environment most of the time. However, the great versatility of these connections and the sheer number of uses that you can give them have made it a popular and tremendously useful service. This is mainly because VPNs provide you with a way to surf the Internet without revealing your personal identity or other information such as data or locations. Using this tool, when your data is encrypted, search engines or ISPs, do not have the ability to see or track your activity on the web.

To better exemplify it, the usual thing is that you have several devices, such as mobile phones, computers or consoles, connected to the same router, for example. In this case, each gadget will be assigned a local IP address, which is not, in any way, visible from the Internet. This refers to a local network, that is, to a set of devices connected in such a way that they can share files and even printers without having to go through the Internet. Well, a VPN connection gives you the possibility of creating a local network without the need for the members that make it up to be physically connected to each other, but rather the process is carried out over the Internet.

Hence the virtual component that was mentioned earlier. Thanks to this mechanism, you will obtain the advantages of a local network, along with a series of benefits that will be enunciated later, with greater flexibility, since the connection is made through the Internet, which allows you to connect from one end of the world to another.

Another relevant aspect of VPNs refers to data tunnels. Normally, when you use the Internet, your device gets in direct contact with your Internet provider, which is in charge of connecting different web services, such as a simple YouTube video. However, when you are connected to a VPN connection, this procedure changes noticeably. Although network traffic continues to be produced from your device to your Internet provider, from there it goes directly to the VPN server, from which it will depart to its destination. Therefore, your connection is encrypted, in such a way that your Internet provider has no knowledge of where you are accessing. In practice this means that your IP address is that of the VPN server.

If you want to see firsthand the advantages that this tool offers, you cannot miss the Free Trial by Surfshark VPN. With it, you will enjoy a private and secure Internet connection. You can also take advantage of unblocked and geographically restricted content and a 30-day money-back guarantee. Its operation is simple: make a DNS request to get the IP address of a VPN server. Subsequently, secret keys are generated to create a secure channel and, finally data encryption occurs.

This will allow you to browse with privacy, hide your location, block ads and malware, safely use public Wi-Fi networks, obtain authentic search results, among many other benefits, and all this on a multitude of devices. Do not think twice, use your VPN now and open the doors to a new world full of advantages.
