The GNOME network details view. I’ve switched the DNS servers to Cloudflare on Fedora 39 with the GNOME desktop. Your ISP usually has your DNS configurations pointing to the router/modem for your network, but that setup might not be as fast or secure as you’d like. Standard DNS servers are unencrypted, which means your web traffic could be visible to others. To improve speed and security, you can switch to different DNS servers, such as those offered by Google or Cloudflare, both of which are fast and encrypted. I’ll show you how to change DNS servers on a GNOME desktop, which can be done on Ubuntu- or Fedora-based distributions.
What you’ll need: A working GNOME desktop connected to the internet. After logging in, click the network icon in the top-right corner and then click Wired Settings. In the resulting window, click the gear icon associated with the Wired connection, then click the IPv4 tab and switch the DNS slider to the Off position. Enter the primary and secondary DNS servers you want to use (e.g., Cloudflare’s or Google’s) and click Apply to save. Finally, click the On/Off slider to activate the changes. Your new DNS servers should now be in effect.
Congratulations! Next, we’ll do the same thing with the KDE Plasma desktop.
