Nope, Google’s quad eights is “recursive DNS server”.

Resolver is usually a part of operating system (sometimes) implementing DNS client functionality and serving as a link between a userland library providing, say, getaddrinfo(), and DNS implementation.

This one is even less than a resolver, it does not implement a library link. It’s a toy DNS client, implementing minimal functionality.

Quad8 is a recursive resolver.

You are referring to a system's local resolver (which is obviously also a resolver, so you are right on this regard).

But still, this project is _also_ a resolver (although obviously not a complete one, it's a learning project).
