You should be doing `dig @1.1.1.1 news.ycombinator.com`

That resolves "news.ycombinator.com" and "1.1.1.1" with your system resolver. You're looking for "dig @1.1.1.1 news.ycombinator.com" which will resolve "news.ycombinator.com" using "1.1.1.1".

Thanks, I wrote that from memory. I'll update my comment.

I think we'll start seeing the standard configuration of 1.1.1.1,8.8.8.8 everywhere. Google/Cloudflare tackled the UX of free DNS spectacularly with these gold IP addresses. It's the primary reason I use them instead of OpenDNS, which was an earlier player in this space.

Just run your own DNS resolver if you value your privacy. With prefetching and caching there will be little difference in performance.

But your DNS will have to query other DNS providers so if you’re the only one using it, it won’t be private.

That tests ICMP echo requests not name resolution.

That is what original test was testing.

What? It says

>Our test was very simple and we performed 70 DNS lookups

That's not ICMP.

Quad9 is supported/funded by City Of London Police, the same police that cooperates with ad companies to track people online. https://www.theguardian.com/media-network/media-network-blog... Keep away from this.

Interesting question: would I rather protect my elderly Mum from known malicious domains potentially trying to scam/phish, or from potential tracking and ad targeting? (Actually, it's not really a difficult choice at all, is it?)

Why not install an ad blocker with a malware blocking list in her browser?

Besides response time, the next level of comparison is how well geo-DNS-based services (global load balancing, etc.) support these resolvers. AFAIK 8.8.8.8 gives decent results in most places, though I've seen suboptimal US-centric results from Quad9 in Asia. Support for RFC 7871 (Client Subnet in DNS Queries) comes into play here too.

9.9.9.9 does not seem to be geographically-aware. Here are the resolutions for the same domain name (CNAME referring to the hopefully closest edge server), from France.

   % dig [domain] @8.8.8.8 +short  
   [id].kxcdn.com.  
   p-frpa00.kxcdn.com. # France

   % dig [domain] @9.9.9.9 +short  
   [id].kxcdn.com.  
   s-us-ca00.kvcdn.com. # America  
   p-ussj00.kxcdn.com.

   % dig [domain] @1.1.1.1 +short  
   [id].kxcdn.com.  
   p-frpa00.kxcdn.com. # France

   % dig [domain] @ns0.fdn.fr +short # My ISP resolver  
   [id].kxcdn.com.  
   p-frpa00.kxcdn.com. # France

But your DNS will have to query other DNS providers so if you’re the only one using it, it won’t be private.

There is 2 main different ways, one which does what you say - the other i'd say is pretty much OK.

If your local DNS server is merely querying an upstream resolver (like 1.1.1.1 / 8.8.8.8) on your behalf, then yes - it is no different.

If however, you query the root nameservers for the glue record for a domain and query the domain's own nameservers directly, then it is pretty good... As you are neither querying your ISP or TheMan.. which means that logically only the domain nameserver owner knows what queries you made (and you are probably hitting that domain in a moment anyway!). (The caveat is that some ISP's do transparent DNS proxying.. in which case, you have much larger trust issues with your ISP and need to take greater measures!)

That said.. I cba with that.

This whole subtree of comments is really messy with all the editing several of you people did.

It would be better to just delete this whole subtree.
