I recently uploaded a video to youtube talking about why ISPs should not be using external resolvers such as google’s 126.96.36.199 to do resolving for their customers. In this post, I am going to give you, The Patreon subscribers, more information on this topic.
Some clarification. Running 188.8.131.52 as your primary resolver is not an evil thing, it’s just not optimal. Whenever I am managing a network I want to squeeze every last bit of performance I can out of it. One way to do this is to run your own resolvers with root hints.
Let’s start with some links
Everything you ever wanted to know about root hints
Setting up Unbound
Do I setup forwarders or root hints?
Do root hints. Bind will cache the lookups. This way you are not dependent on another entities DNS servers
My upstream ISP has DNS servers. Should I use them?
This is better than nothing, but I would ask them where those servers are located. It’s really not that hard to run your own.
