Cloudflare vs Quad9

Recommended Posts

Posted · Original PosterOP

Looking to use a different DNS provider than my ISP because they block porn sites (lol). Firing up DNSBench, here are the results:

 

Seems like Cloudflare is far and away the fastest for cached, though for uncached and DotCom, they're just around average. Ignoring UltraDNS and whatever NTT America is, Quad9 is the next well-known provider that provides average speeds for cached but is considerably better than Cloudflare for uncached and DotCom.

 

Here's the tabular data for the two DNS providers.

 

   1.  0.  0.  1 |  Min  |  Avg  |  Max  |Std.Dev|Reliab%|
  ----------------+-------+-------+-------+-------+-------+
  - Cached Name   | 0.010 | 0.010 | 0.011 | 0.000 | 100.0 |
  - Uncached Name | 0.010 | 0.112 | 0.244 | 0.071 | 100.0 |
  - DotCom Lookup | 0.032 | 0.036 | 0.041 | 0.002 | 100.0 |
  ---<-------->---+-------+-------+-------+-------+-------+

Also, Quad9 has malware protection, which is a plus.

What do you guys think, which of the two should I go for?

More importantly, Cloudflare is pure DNS, no meddling.  Quad9 as I understand it DO meddle, they are meant to block certain hosts, so its a rather different thing.  This is also why I don't touch OpenDNS, I don't want anyone messing with my DNS but me, any overrides I do on the router with unadulterated DNS coming into it via Cloudflare.

 

Plus its not all about response time, for better security you can use DNS over TLS which will sacrifice some speed for the benefit of your ISP not being able to snoop on or intercept your DNS lookups.

If I weren't using DNS over TLS, I'd probably use full DNS resolution on the router, as you aren't relying on a third-party DNS cache being accurate that way.


Router: i5-7200U appliance running pfSense WiFi: Ubiquiti nanoHD (~700Mbit peak throughput)
ISP: Zen Unlimited Fibre 2 (66Mbit) + Plusnet Unlimited Fibre Extra. (56Mbit)
