A lot of browsers will enable DNS Over HTTPS automatically and use their own DNS servers. The hosts file can only be used to block internet traffic if your browser is deferring to the DNS Server specified in the Windows operating system.

DOH encrypts your DNS requests so that they can’t be intercepted and read by third parties that might be snooping - in general, this is a great thing.

Like Windows, Ubuntu’s hosts file is located in the /etc/ folder, though here it is in the root of the drive. For this example we will use Vim, since it is one of the traditional text editors in Linux. You can use your favorite command-line editor or your favorite GUI text editor. In Ubuntu (and most Linux distributions) you can edit the hosts file directly in the Terminal.
