When browsing, we prefer to stay anonymous. That is why we make use of Virtual Private Network (VPN). With this, we can mask our location from the sites we have visited with just a few clicks. However, our use of the VPN will be for naught when there is a DNS leak. Domain Name System or DNS is a system that can link IP addresses and URLs. Whenever we browse the internet, a request where the URL we have visited is contained is sent to the DNS Server. This then will point the right IP address where it came from.
When there is a DNS leak, the browsers are ignoring the use of VPN and the DNS request is being sent to ISP directly. This led us to believe that we are still anonymous online even if we are not anymore. To prevent this from happening, you should run a DNS leak test. Here is how you should do it.
This problem is not obvious when the default setting is the one being used by your computer. This is also the case when the computer is not routing application for DNS with the DNS server for the VPN. In this case, you really need to take the test for DNS leak. The test can be found at https://cryptoip.info/dns-leak-test. You will know your status of your DNS leak after this test is run. Then, you will know how to continue appropriately.
Change your DNS Server
One of the best ways to ensure that your ISP cannot monitor your activities online is through changing the DNS server. Even when the DNS leak is not much a concern for you, there are still benefits that you can get from doing this such as faster internet speed. There are many DNS servers that can provide you with the performance and security that you need from DNS leak.
Use Monitoring Software for VPN
When there is a DNS leak, you can use some monitoring software for VPN that offers support in this case. If you are a concern with the security hacking online and the DNS leak, using this kind of software can help you.
Use VPNs that are protected from DNS leak
There are VPNs that have properties to monitor the DNS request, this way, you can have the assurance that the request will go to the VPN and not in the ISP. To check if your VPN has this property, just go to Settings and you should you see the option to prevent DNS leak if there is any.
This technology can cause DNS leak. If you have no use for it, it would be better to simply disable it.
Staying anonymous online makes us feel freer to explore and it gives us the feeling that we are somehow secured. This freedom and security are both loss when there is a DNS leak. With that, we should at least run a test to identify if there is a DNS leak lurking on our computer. After this, we can have a clear idea as to what action we should take first.
