What is a DNS Leak?
When you use a VPN, it makes a connection between your computer and its server, and then the VPN server connects you to the website that you queried for. on the other hand, whilst you are notusing any VPN, and also you kind a website address inside the browser, then hit input, your IP server at once connects you to that unique internet site. but with VPN, your connection is filtered through their server and the connection is especiallyencrypted. This way, your ISP or authorities can only see that your computer is hooked up to a VPN server, however they can’t see wherein the VPN connects you. meaning no one can track which web sites you have got been surfing. that’s whatVPN for. however, a state of affairs where the VPN is bypassed is called a DNS Leak. In simple words, if your browsing can be tracked even you are using a VPN; it is called a DNS Leak.
This is a kind of dangerous situation because as a user you don’t even realize that your VPN is bypassed, and all of the time you keep thinking that you are anonymously surfing the netbut the fact is that your logs are being tracked.
you would still be able to unblock the blocked websites in your vicinity because you are the use of the VPN, but your anonymity is left unprotected which at once approach that your location and browsing are being logged by means of your ISP.
