DNS performance tests - Cloudflare, Google, ISP

Post date: Apr 8, 2018 7:26:52 AM

Run DNS server benchmark. Well sure, Cloudflare (1.1.1.1) is doing great, but ISPs servers aren't that bad either, as usually is being claimed. People often claim that Google DNS is great, but it isn't. Many of the other "better alternatives" are also horrible compared to ISPs or Cloudflare's DNS servers, and also provide consistently bad performance. In this case the Telia DNS servers are the old Telia DNS servers 18.18 and 19.19 which have been used for long time. And it seems that for fiber connections the DHCP delivers alternate DNS servers, which are the two last DHCP servers. As far as I can see, the ISP DNS isn't bad at all, it's actually quite good. For local public DNS tests, I also included Trex.fi DNS which got quite an deviatio, because ICMP Echo time (PING) is just 4 ms.
