I already know that private DNS is important for privacy. I’m using Quad9 btw.
But recently I hear a lot about NextDNS and similar providers that give more advanced features such as custom filters and domain blocking. I’m getting interested in that topic now as I have to use some proprietary apps with a lot of trackers in them.
However I’m really struggling to find useful information about what domains to block, what settings to use in one or another use case etc. I don’t have much experience with firewalls and server stuff either which makes it even harder.
So, could anyone share some good resources on this so I can get started? Or should I just not worry about it and use a whole other system such as firewall?
IMHO An old PC or Raspberry Pi + Pi-Hole or AdGuard Home is the way to go. Set up Wireguard if you need to use it outside of home, or if Youre adventurous you could buy a domain and expose DoH over port 443. Both softwares provide you with built in block lists. Then you can use quad9, adguard, nextdns, mullvad, really any provider with a good privacy policy you trust for that DNS server you set up. Hell you could even do your own with unbound
