If one browser is using encrypted DNS while another, on the same computing device, is not, then expect these tests to show different results in each browser. The most recent change is that web browsers can now specify their desired DNS server. We need tests like these because there are many places that DNS servers could have come from. That is, they report the DNS servers your current browser is actually using. You can check a computer or router to see what your DNS servers should be, but the pages below show what they actually are (with the tested web browser).

The system that translates names into the underlying numeric IP addresses is called DNS (Domain Name System) and the computers that do the translation are referred to as DNS servers.ĭNS Servers are extremely important. All communication on the Internet is based on these unique numbers, website names and computer names are just a convenience. You know this site as and its IP address is 216.92.136.14.
