Looking Block specific websites by domain (not IP)

what I use for this purpose is /etc/hosts.

  1. add list hostname_config '/etc/hosts' to config resolver 'kresd' section in /etc/config/resolver file

  2. add 127.0.0.1 youtube.com to file /etc/hosts. Replace youtube.com with your domain.

  3. restart resolver [command: /etc/init.d/resolver restart] or the router

As you can see, it can be used for simple ad blocking on all devices, including TVs.
