That would be a 'recursive resolver'[0], which recursively queries the DNS hierarchy from the top, returns the requested DNS record, and (unless you configure it not to do so) caches the results.

They're easy to set up and unless you're using it to support thousands of DNS requests per second, it's not appreciably (on human scales) slower than forwarding requests to your ISP's servers and/or 8.8.8.8 or 1.1.1.1.
