I already gave quad9 a try, but instantly saw ads, which is really annoying imo

You can use different DNS server settings like
Google (8.8.8.8; dns.google.com)
Cloudflare (1.1.1.1; one.one.one.one or the more 'secure' versions which are 1.1.1.2; security.cloudflare-dns.com)
Quad9 (9.9.9.9; dns.quad9.net)

The one I personally use is Adguard which is the one above

なので、NextDNSやAdGuardHomeで設定すべきフィルターやDNSは大体テンプレみたいなのがあると感じる

例えば広告ブロックならAdGuard DNS Filterを使うか、あるいはEasylist+Easyprivacyのどちらを使うかだったり、マルウェアブロックならQuad9を使いつつOnline Malicious URL Blocklistを加えて検出率を高めたりって感じかな

基本的にはマルウェア•ウイルス•フィッシング等のフィルターは誤爆は少なかったと思う

あとQuad9はフィルターのソースこそ公開されてないものの、検索エンジンに引っかかるようなものの悪意のあるドメインは他より高確率でブロックできていた記憶がある
まあもっともこれは感覚的にはなるが…

Cloudflare DNS worked for me when my Discord mobile got fucky, but for some, Cloudflare or Google DNS might not work.

My friend used quad9. Whichever works for you really.

hop on cloudflare one or quad9 twin

マルウェア、フィッシングを防ぎたいなら Quad9 よりも AdGuard か

I fed Cloudflare, Quad9, NextDNS, and AdGuard the same malicious domains to see who actually stops them

Cloudflare、Quad9、NextDNS、AdGuardのそれぞれに同じ悪意あるドメインを入力し、実際にどこがそれらをブロックするかを検証しました。

Four resolvers walked into a malware test and consistency did not follow.

Private DNS (with ad blocking) for newer users or those unfamiliar
submitted by unitedwithme to foss 15 points | 4 comments I responded to someone in comments on a post that may not get as much visibility, and wanted to share something that might help some others who are newer to this. I referenced Quad9 DNS as probably one of the best private DNS you can use, Swiss based, no log, no tracking, no data to sell, etc. They also implement DNSSEC, DoH, DoT, QUIC, ECS (which you may or may bot want), malware blocking, content filtering, and maybe something else I’m forgetting. Many DNS sinkhole apps, OSes, or systems can actually utilize Quad9 for your resolver while those systems also block ads. Below is my functional list of systems that I’m aware of, though I haven’t tested everything. I believe all are considered FOSS, too. **If you don’t have a spare Raspberry Pi laying around, try running in HomeAssistant, Yunohost, ZimaOS (previously CasaOS), or others.** DNS sinkhole (Adblocking) apps: 1. Pihole 2. eBlocker 3. Technitium 4. AdGuard 5. uBlock Origin Feel free to comment and add your own I’m maybe not aware of. I’m no software engineer, but I can read through some code, though not an expert, nor have combed through these personally. Usually I’ve tested/run at the recommendation of others over the years before my ban on Reddit (for shitting on AI). Hope this helps!!

Spent way too long trying to install Technitium on Rocky Linux 10.2 Learned a lot but ultimetly im going to have to scrap it and punt to Rocky 9.x. the Quad9 forwarder with Quic doesnt want to work because it needs a .net library that refuses to install

Finally stopped being lazy and pointed my household router to the Quad9 DNS (@quad9dns.bsky.social operated by the Swiss-based Quad9 Foundation) 😎
