This resolver has the lowest overhead of any resolver and typically approaches the speed of the unmodified :mod:`socket` functions.

This can be useful during debugging, or it may be a good choice if your operating system provides a good caching resolver (such as macOS's Directory Services) that is usually very fast and functionally non-blocking. .. versionchanged:: 1.3a2 This was previously undocumented and existed in :mod:`gevent.socket`.
