Alternatives to AdAway
(github.com)
I use ublock origin for my browser and use Mullvad DNS with content blockers. I don't know what VPN you use but as long as you can set your own DNS then Mullvad servers should work.
If your router allows you to set the DNS server you can block ads network wide.
Does anyone know if this DNS adblocker is safe to use? I tested it briefly and it seems to work as well as rooted AdAway
