-class Resolver(AbstractResolver):
-    """
-    Implementation of the resolver API using the `c-ares`_ library.
-
-    This implementation uses the c-ares library to handle name
-    resolution. c-ares is natively asynchronous at the socket level
-    and so integrates well into gevent's event loop.
-
-    In comparison to :class:`gevent.resolver_thread.Resolver` (which
-    delegates to the native system resolver), the implementation is
-    much more complex. In addition, there have been reports of it not
-    properly honoring certain system configurations (for example, the
-    order in which IPv4 and IPv6 results are returned may not match
-    the threaded resolver). However, because it does not use threads,
-    it may scale better for applications that make many lookups.
-
-    There are some known differences from the system resolver:
-
-    - ``gethostbyname_ex`` and ``gethostbyaddr`` may return different
-      for the ``aliaslist`` tuple member. (Sometimes the same,
-      sometimes in a different order, sometimes a different alias
-      altogether.)
-    - ``gethostbyname_ex`` may return the ``ipaddrlist`` in a different order.
-    - ``getaddrinfo`` does not return ``SOCK_RAW`` results.
-    - ``getaddrinfo`` may return results in a different order.
-    - Handling of ``.local`` (mDNS) names may be different, even if they are listed in
-      the hosts file.
-    - c-ares will not resolve ``broadcasthost``, even if listed in the hosts file.
-    - This implementation may raise ``gaierror(4)`` where the system implementation would raise
-      ``herror(1)``.
-    - The results for ``localhost`` may be different. In particular, some system
-      resolvers will return more results from ``getaddrinfo`` than c-ares does,
-      such as SOCK_DGRAM results, and c-ares may report more ips on a multi-homed
-      host.
-
-    .. caution:: This module is considered extremely experimental on PyPy, and
-       due to its implementation in cython, it may be slower. It may also lead to
-       interpreter crashes.
