VPN and privacy are two terms that go hand in hand. We use applications of this type to be able to protect our data when browsing the web. For example, when using a public Wi-Fi network, where there may be risks. Now, it is essential to keep in mind that there could be problems if we make mistakes or use a program that does not work well. Therefore, we are going to talk to you about one of the main reasons why your privacy may be at stake if you use a VPN to browse.
Using a bad VPN will not only prevent you from accessing blocked sites or hide your IP, but it could even allow malware to enter. It is key to choose a guarantee program and make sure that it will not compromise your personal data or the proper functioning of the device.
DNS leak
A major problem when using a VPN is what is known as a DNS leak. DNS is the acronym for Domain Name System. Basically, it is what allows you to access a web page, such as RedesZone, without needing to know its IP address and only entering the domain name.
There are different DNS servers and you do not need to use the ones assigned to you by the operator. You can use, for example, those from Google or Cloudflare. What a good VPN does is keep those DNS requests hidden. A measure that protects privacy and avoids problems. Among other things, it will prevent your operator from knowing what websites you visit.
Now, what happens if there is a DNS leak? That privacy improvement is going to come to nothing. A third party could know what websites you are visiting, could know more about you and, ultimately, even attack you by having more information. This is what is called a DNS leak and is nothing more than using a VPN that does not protect properly.
Therefore, this is the reason why your privacy can collapse when using a VPN for browsing. Even if you think you are completely protected, in the event of a DNS leak, your data could end up in the wrong hands.
How to prevent it from happening
So what can you do to prevent this from happening? It is essential that you use a reliable VPN. You can always see reviews from other users or independent reports that have analyzed that program. This will help you avoid problems and ensure that your personal data is always protected.
In addition, it is good to correct problems in the VPN. If you notice that it does not work well, that it cuts out or you have problems navigating, perhaps there is something wrong with that application you are using. It is key that you review it and see where the problem may be, so that you can take action as soon as possible.
In short, as you can see, having DNS leaks is a major problem when you are going to use a VPN. It is key to use a guaranteed service that works correctly and not have problems. Your privacy is at stake and you must take measures to avoid problems of this type when browsing.
