DNS Resolvers Performance compared: CloudFlare x Google x Quad9 x OpenDNS
Ping's help us measure latency and distance between our testing servers and their DNS servers. London, Paris, Amsterdam, Frankfurt Asia: We removed them from the results as their ping tests were way above ms for all locations.

Why should you try Google Public DNS?

OpenDNS Vs. Google DNS

If there is a line containing domain-name-servers , write down the IP addresses for future reference. Every router uses a different user interface for configuring DNS server settings; we provide only a generic procedure below. For more information, please consult your router documentation. Some routers use separate fields for all eight parts of IPv6 addresses and cannot accept the:: DNS servers are typically specified under advanced Wi-Fi settings.

However, as every mobile device uses a different user interface for configuring DNS server settings, we provide only a generic procedure below.

For more information, please consult your mobile provider's documentation. From your browser, enter a hostname URL such as http: If it resolves correctly, bookmark the page, and try accessing the page from the bookmark.

From your browser, type in a fixed IP address. You can use http: If this test does not work, you do not have access to a NAT64 gateway at the reserved prefix If this works correctly, bookmark the page, and try accessing the page from the bookmark.

Roll back the DNS changes you made and run the tests again. If the tests still do not work, then there is a problem with your network settings; contact your ISP or network administrator for assistance. If you encounter any problems after setting Google Public DNS as your resolver, please run the diagnostic procedure. This will revert your settings to using your ISP's default servers.

If you need to manually specify any addresses, use the procedures above to specify the old IP addresses.

But see for yourself. The DNS lookup test was done using the dig utility and extracting the "Query time" from the results.

For each domain we tested it a 5 times, with a few minutes within each one. We removed the worst response and averaged the others to reduce the chance of a latency from our test location affect the results. All those providers, except for Yandex, have an anycast network, so they performed very well. Yandex seems to be restricted to Russia, so had very high ping times compared to the others. We removed them from the results as their ping tests were way above ms for all locations.

Norton does not allow ICMP, so could not be tested. We consider any response under 5ms to be pretty strong and equal between each other as they are undistinguished for the end user. Responses between ms are acceptable OK and anything between 20msms we consider to be slow.

Ping responses higher than ms get a FAIL as it means there is not presence on that location or somewhere close by. All providers performed really well, but both Google and Quad9 got 1st 5 times out of the 14 locations. CleanBrowsing came out in 3rd, being the faster in 3 locations. However, when we consider the average across allow all locations, Quad9 did not perform as well, as it had very high ping time from Sao Paulo, Tokyo and Dallas.

In my case this meant that iTunes downloads were coming down at a couple of hundred kilobytes per second rather than the 1. As a result you will be charged for those downloads.

The location of the IPs DNS determines where your request gets resolved, per the note from venkin below. There is no need to share the physical location of the servers, as the 8. For example, in the uk, i get the uk dns server, when i go to the US, i get a server in the US — all using that one ip address.

I started investigating when I was taken to servers in Japan and Korea for India-based services. Your second point is simply not true John. If your network adapter is still pointed at the DNS say….

Which is why DNS servers exist in the first place! John Wood, better late than never. Your point is correct. Google does not have just one set of servers at those IPv4 addresses but many. That was with just IPv4. IPv6 brings on a whole new set of complications. I will need to also handle IPv6 fairly soon. Now, lets lower the boom. More on that in a moment. Is the beast dead or not?

If it is dead not in DNS say it is dead and more on. But you want it to really show that it is dead in a script and how is the DNS server to know that you are interactive or using a DNS checking script? I have two main activiites. One is review Phish at PhishTank for whether they are still a phish or not. I also help at MalwareDomainList and for myself in block lists of malware hosts. The last thing I need is a DNS service or something else between me and what ever saying this host has phish or malwre.
