I read a bit about using a different DNS for Privacy and I think the best one should be quad9? Or is there anything better except self hosting a DNS?
- I use Quad9 for my upstream. - This! 
 
- Using NextDNS for quite long time 
- I use cloudflare dns 
- Quad9 is decent, but there’s some weird legislative issues (they can be court ordered to not resolve certain sites) BC weird reasons. - If you have a raspberry pi or similar sitting somewhere, you can set up a pihole DNS with unbound as upstream. Then you’ve got a DNS that’s as private as you want, locally cached and with additional ad/malware/… blocking capabilities. 
- I use NextDNS, but also use Cloudflare sometimes. 
- The one from your ISP. Your ISP can see your traffic anyway, so you gain nothing by using a third-party DNS server. - That’s not true at all. If you’re after the fastest DNS for loading / response times then the ISP DNS would be ideal. For privacy you’d want one that can offer ad and tracking protection like NextDNS. - Okay, maybe I got the question wrong. If you care about content blocking, then you are right (though I’d prefer self-hosted resolvers like pi-hole or AdGuard Home over third party resolvers). - You can use pihole as your main resolver and NextDNS as your down stream resolver as well for layered protection. That’s what I do. Works well. NextDNS is free protection up to 300,000 queries a month. If you go over it just acts like any regular resolver. The paid plan is inexpensive too. - If you use the same or similar blocklist it does not provide additional protection though. - That’s true yes. 
 
 
 
 
- As far as I read (I’m no expert!) they could check the SNI of the TLS handshake if they want. But using the DNS of the ISP is handing them the data right in a way they can analyze/use them very easily afaik? - Still learning about this topic! - They route your traffic, hence they can see all IP addresses you communicate with. With a reverse lookup you can then usually find out the address too. - [This comment has been deleted by an automated system] 
 
 
 
- I’m not an expert on what makes a “good DNS”, but I have been using a pi-hole for about 5 years and it has been super stable the whole time, despite my best efforts.
