DNS Question

[Jimkirk363]

Now i know this may sound like a daft question but im just wondering what DNS people use and if they have any issues with it.

Im currently using Cloudflare 1.1.1.1 but finding downloading slower than using Virgins own DNS, i can hit 51mb/s on Virgin Medias DNS but on cloudflare between 29 - 35mb/s only especially on US based sites.

Ive asked Virgin and they claim not to be oversubscribed and not to have any issues so i have to look elsewhere...

Thanks Guys.

How many times have you tested? How are you testing?

DNS is just resolving a website to an IP address and in 99.99% of cases won't have an impact on transfer speeds, aside page load times, once everything is resolved.

This, DNS might affect how quickly a download starts (unlikely to a level you would notice) if you're resolving a different domain.

But will not affect download speeds.

CloudFlare it is. Plus they have okay privacy policy.

As others have stated, DNS only impacts how long it takes your computer to find the address of a site that isn't already known. Once it's found, your DNS configuration has zero impact on the actual transfer rate of the site.

 

We have 350/20 with virgin media and outside of speed tests and CDN/multihomed downloads like Steam, it's rare that we get that all the time. The line is definitely capable, but it's rare that every part of the link between our home and the site we're accessing is set up to transfer data at those kinds of speeds. 

 

As for our home setup, we have a dnscrypt proxy set up to encrypt all DNS queries, with cloudflare (DNS over HTTPS, DoH) as our primary resolver. If Cloudflare fails to resolve for any reason, we fall back to a short list of other resolvers, but it's very rare that this happens.

Are you just changing DNS and running speed test?  That's not the appropriate way to test DNS.

 

You can run this benchmark to see what endpoints resolve the fastest for you.

For DNS queries you're purely looking for the lowest latency for responses.  After the name resolves there isn't any DNS component that will dictate your speed test for general bandwidth usage or transfers.
