I love NextDNS, does everything I need it to.

I found https://nextdns.io easy to use with good free plan - 300,000 queries/month

I use AdGuard’s public DNS. Mostly because it’s free. https://adguard-dns.io/en/public-dns.html

I’ve been using nextdns

I used Mullvads, now I use AirVPNs. Have not decided yet if I go back.

I personally use unbound, so you are basically your own recursive DNS resolver… First few days might be tad slower until you start caching results. But eliminates having to trust a third party, i instead of ISP & google/quad9/cloudflare etc. Its only your ISP your having to somewhat trust

I like Quad9.net

I use Control D. They operate a few resolvers.

• p0.freedns.controld.com - filters nothing
• p1.freedns.controld.com - filters malware
• p2.freedns.controld.com - filters malware + ads
• p3.freedns.controld.com - filters malware, ads, and social media (obviously not fediverse stuff since there are so many). This is the one i use.

On android, I use rethinkDNS. Its pretty configurable and open-source. On windows or linux, I use mullvad dns. They have 2 free DNS resolvers(unfiltered, adblock)

I would encourage you to find one that fits your needs at DNSCrypt, or Privacy Guides, or Privacy Raccoon. Which will provide some basic information about a DNS resolver, then you can do more research as you see fit.

As a heads-up, some will block ads for you and some won’t.

I’m a happy user of Control D. They have a free dns resolver on their page, you can choose which filters to apply. If you want more control you can get a paid subscription.
