My hosting provider runs no DNS servers and recommends using 8.8.x.x, so I have to pick something.
You don't have to pick, and this is not meant to be patronising. Install Unbound with the few lines of configuration I posted earlier in this thread, and set your /etc/resolv.conf to "nameserver 127.0.0.1". Unbound will contact upstream servers as required. You don't have to configure *any* upstream servers manually.
See https://en.wikipedia.org/wiki/Domain_Name_System "Address resolution mechanism" for what will happen under the hood.
