How to tweak your DNS values to get speed and privacy improvements

Domain Name Servers (DNS) are the Internet’s equivalent of a phone book, they maintain a directory of domain names and translate them to Internet Protocol (IP) addresses. Each device connected to the Internet has a unique IP address which other machines use to find the device. DNS servers eliminate the need for humans to memorize IP addresses such as (in IPv4), or more complex newer alphanumeric IP addresses such as 2400:cb00:2048:1::c629:d7a2 (in IPv6).

The DNS servers are nothing more than the translators that allow you to connect to the websites by typing in simple textual addresses (e.g. instead of the very long numerical addresses (e.g., which would be the real coordinates of Internet sites.

By default, our PCs and routers DNS are crappy and flaw. There are many disadvantages in the default operators DNS, for example, they are not very reactive and make navigation slower, they block certain websites, they do not care about your privacy and many other shitty things.

How to set up and configure new DNS in Linux

While these steps are perfect for Fedora, Ubuntu and the most part of the Linux distributions that configure DNS settings through the Network Manager, alternatively, you can specify DNS settings in /etc/resolv.conf file.

Open Settings (or Control Panel) and then click Network. Find your Internet connection in the right panel, then click on the gear icon. Click the IPv4 or IPv6 tab to view the actual DNS settings.

Set the “Automatic” DNS switch to Off, then provide the address in the DNS entry field and in the alternative DNS entry field. Optionally, for the IPv6 standard, you can use 2606: 4700: 4700 :: 1111 and 2606: 4700: 4700 :: 1001. In the end, click Apply and restart the system.

Old school, in a terminal session:

$ sudo vi /etc/resolv.conf

And add these at the end of the file:


That’s all.
