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?
Have a look at RethinkDNS, https://docs.rethinkdns.com/dns/ their wiki is pretty good. They have recommended block lists, and also have a feature that let’s you search inside block lists to see what they actually cover.
If you are on Android they have a companion app, you do not need to use it though. The app adds a good firewall (capture and redirect port 53 for example) and detailed logs if you want. You can block domains and specific IP addresses.
It’s all FOSS too
I was recommended by a well-known privacy guide to use Rethink with AhaDNS Blitz, but it seems to fail often; nothing resolves until the VPN is stopped and restarted. Any ideas or advice?
I don’t have any experience with AhaDNS Blitz.
With RethinkDNS I have had occasional failures on their Max resolver, changing to Sky then works. That has only happened two times though, and was fixed with a few hours.
Sorry I can’t be more help.
