What Hacker News says
4 sourcesHere's an open source nameserver that helps ID DNS resolver in use: https://github.com/redirect2me/which-dns
In DNS0: The European public DNS that makes your internet saferI've added an "Alternatives" section [1] to the README with several of the sites/services/etc mentioned in this HN thread.

In Show HN: Which DNS servers are you pointing to?I kept running into DNS issues, and needed to triple-check that I was pointing to the right DNS servers, so I made this utility website that does exactly that: which-dns [1]
This isn't a new idea ([2]), but mine supports https (hat tip to Matt Holt's certmagic [3]), is ad-free, and the source is available [4].
