11/7/2023 0 Comments Surfshark dnsSince we already have a VPN connected, in theory, all our requests should be resolved by our VPN providers region based IP but when that doesn't happen due to the above reason, it is called a DNS leak. This automatically means that even though we're using a VPN, all our requests are still going through our ISP and it can be tracked by them.īasically they can see any request that we're making and they have a whole list of each and every website that we visit. What is a DNS LeakĭNS Leak is when we use a VPN but we do not change our DNS resolver which ends up with all our DNS requests going through the ISP, instead of the VPN providers nameserver.Ī DNS Leak happens when we use a VPN but we do not change the nameserver that's resolving our requests. However, most ISP's use their own DNS servers, this helps that, in way, restrict certain region locked content. There are various nameservers, Google's nameserver is 8.8.8.8 and Cloudfare's is 1.1.1.1. So we tell our computer to resolve the DNS by using a nameserver which we provide by passing a nameserver IP address or a domain name. Now, this nameserver probably has some kind of IP address too or a domain name. We need to provide it a nameserver (think of it like a mapping of domain names to IP addresses) so that the IP address can be found. So DNS is what finds out the IP address of the server that is mapped to the domain we're trying to visit. So that domain name has to be mapped to an IP address that serves the content. Whenever we visit a website, we type in a domain name on the browser. You can skip to the next section if you know what and how it works! What is DNSĭNS, in laymens terms, finds out the IP Address of a domain that you're visiting. What is it?īefore we dive into what a DNS Leak is, let's understand what DNS is. NOTE: SurfShark DNS Leak test might show DNS is leaking if your VPN is not from theirs. That can be tested with a site like dnsleaktest or SurfSharks DNS Test. What I am talking about is the DNS Leak issue. Since that package is probably using OpenVPN under the hood, it was only possible that my setup might also be facing that issue. I would not have known that this was an issue had I not checked the comments on the SurfShark AUR package. After I setup OpenVPN with SurfShark which I wrote about in this article, I actually faced an issue.
