N/A __future__ absolute_import division print_function with_statement N/A pycares N/A socket tornado gen tornado.ioloop IOLoop tornado.netutil Resolver is_valid_ip CaresResolver N/A Resolver N/A N/A Name resolver based on the c-ares library.

    This is a non-blocking and non-threaded resolver.  It may not produce
    the same results as the system resolver, but can be used for non-blocking
    resolution when threads cannot be used.

    c-ares fails to resolve some names when ``family`` is ``AF_UNSPEC``,
    so it is only recommended for use in ``AF_INET`` (i.e. IPv4).  This is
    the default for ``tornado.simple_httpclient``, but other libraries
    may default to ``AF_UNSPEC``.
