What is a DNS leak?
DNS is a technology which resolves hostnames to IP addresses, which is a cornerstone on which the internet is built, so you don't need to remember the IP addresses of websites you want to visit. For example a DNS query to google.com resolves to the IP address 126.96.36.199.
In case you establish a VPN connection, the VPN tells your operating system to use hide.me DNS servers, so your ISP can't see anymore which websites you want to access. Now that's where a DNS leak might occur, because if your system assigns a lower priority to these DNS servers, it might continue using the DNS servers from your ISP and resolve queries inside your local network outside the VPN tunnel.
Does hide.me VPN protect against DNS leaks?
Our VPN does indeed protect from DNS leaks. We have our own DNS servers that keep no logs, so your queries are encrypted inside the VPN tunnel. Furthermore we store nothing about the websites you visit or the services that you use.
There can be instances outside of our control, that means your DNS queries are being leaked. Take Teredo for example, a built-in Windows feature. It was built to improve compatibility between IPv4 and IPv6, but it can lead to DNS leaks. You can easily disable it by entering “netsh interface teredo set state disabled”.
Why could I have a DNS leak?
There could be a number of reasons as to why you have a DNS leak, even when connected to our VPN servers. Probably the most common one is that your router acts as DNS relay and sets a local IP address as DNS in your network settings. Your OS prioritizes this DNS server and since local network connections are not tunneled over the VPN, your DNS queries are resolved over your unprotected internet connection.
If you're not using our apps that take care of proper DNS configuration, you can mitigate this issue by setting a public DNS in your network adapter.
What’s the best way to set up my VPN to avoid DNS leaks?
The best thing you can do if you want to avoid DNS leaks is to use our app that is available on a wide range of devices. We have applications for Windows, MacOS, Android, iOS, and much more. The app is easy to set up and use and comes with great features such as a kill-switch.
