Whether 184.108.40.206 makes your connection faster depends on the region you live in, you should test it to see whether the switch makes sense. For example, I used Google DNS (220.127.116.11 and 18.104.22.168 for ipv4 and 2001:4860:4860::8888 and 2001:4860:4860::8844 for ipv6) before that (learned years ago that it might make the connection faster & safer), then switched to 22.214.171.124 and 126.96.36.199 ipv4 / 2606:4700:4700::1111 and 2606:4700:4700::1001 /ipv6 after coming across this thread yesterday. Then downloaded DNS Benchmark tool (free, saw it recommended in reddit discussion about pros and cons of 188.8.131.52 thing; it tests & compares various public DNS resolvers available to you; I'm sure there are plenty of alternatives for other OS) to see if the switch actually happened and whether I benefited from that switch, and… …bad news — it's a tie between 184.108.40.206 and Google DNS in terms of speed. Access to cached & uncached lookups is a bit faster with 220.127.116.11 but dotcom lookups are faster with Google DNS to the level that this difference fully makes up for the [cached + uncached lookups] speed difference of 18.104.22.168. Bottomline: test the speed of 22.214.171.124 for YOUR location, compare it to your other options, don't buy into the hype blindly.
