In this "Lite" version of Chit Chat Across the Pond (within a NosillaCastaway's definition of Lite), Bart teaches us about DNS Resolvers and helps give us the information to choose the right one for us. To get us there he starts by explaining the background technologies. He explains DNS and how there's two kinds of servers, he explains DNS Name resolution and why caching is important, and the security problems (and solutions) of DNS. Then he explains how third-party DNS providers can solve some of these problems. He explains their motivations which will inform your own decision. Finally (at about the 1 hour mark) he walks through the solutions offered by OpenDNS, Google, Quad9 and Cloudflare. I loved this episode and you can tell Bart really loves talking about DNS.
