Quad 9 Replacement with 1.1.1.1 #34

Closed sengsational closed 5 years ago

sengsational commented 5 years ago

Using Steve Gibson's DNS Benchmark shows a rather slow DNS result when the EdgerouterX is configured as in the PDF. I learned quite a bit going through the PDF, so I can probably just reconfigure this myself, but I thought I'd mention it here, since there might be a change offered in the next revision of the PDF.

Hi,

I just ran the benchmark and Quad9 was slower for me also. You will have to make a security vs speed trade off for yourself. I will probably add something similar to the following in "Section 20 - About DNS Settings" the next time I update the guide:

"Some people are reporting that Quad9 is slower, See Section 73 - Adblocking and Blacklisting as a possible security alternative."

Thanks, -Mike

@sengsational I too find Quad9 a little slower but I wonder if it matters that much since you would be hoping for most lookups to come from your router's cache which is extremely fast. Also I wonder if you have some problem in your setup or with your service as you seem to have a lot of failures on most of your dns servers. You don't give the scale so its hard to tell just how bad it is. My own dns benchmark is here DNSbenchmark.png. Full scale is 100ms (20ms/div). I have set my dns addresses in the dns service with dns forwarding to system disabled and no addresses set in system.

I have just posted on the forum about dns forwarding settings Making-sense-of-DNS-forwarding-options, which you may find of interest @mjp66 .
