Benchmarking DNS resolvers on Android
Have you ever wondered which DNS resolver is the closest to your location? There is an Android app called DNS Speed Test that I have been using for a long time that allows to make latency tests on the go. As you can see here in Seoul Cloudflare is by far the fastest, since I hit the Seoul PoP. For some reason Google makes me go through North America according to traceroute/mtr, hence the difference.
