Returns a list of socket objects (multiple sockets are returned if the given address maps to multiple IP addresses, which is most common for mixed IPv4 and IPv6 use). Address may be either an IP address or hostname. If it's a hostname, the server will listen on all IP addresses associated with the name. Address may be an empty string or None to listen on all available interfaces. Family may be set to either `socket.AF_INET` or `socket.AF_INET6` to restrict to IPv4 or IPv6 addresses, otherwise both will be used if available. The ``backlog`` argument has the same meaning as for `socket.listen() <socket.socket.listen>`. ``flags`` is a bitmask of AI_* flags to `~socket.getaddrinfo`, like ``socket.AI_PASSIVE | socket.AI_NUMERICHOST``. ``reuse_port`` option sets ``SO_REUSEPORT`` option for every socket in the list.

When a connection is accepted, ``callback(connection, address)`` will be run (``connection`` is a socket object, and ``address`` is the address of the other end of the connection). Note that this signature is different from the ``callback(fd, events)`` signature used for `.IOLoop` handlers. A callable is returned which, when called, will remove the `.IOLoop` event handler and stop processing further incoming connections. .. versionchanged:: 5.0 The ``io_loop`` argument (deprecated since version 4.1) has been removed. .. versionchanged:: 5.0 A callable is returned (``None`` was returned before).

By default, a blocking implementation is used (which simply calls `socket.getaddrinfo`). An alternative implementation can be chosen with the `Resolver.configure <.Configurable.configure>` class method:: Resolver.configure('tornado.netutil.ThreadedResolver') The implementations of this interface included with Tornado are * `tornado.netutil.DefaultLoopResolver` * `tornado.netutil.DefaultExecutorResolver` (deprecated) * `tornado.netutil.BlockingResolver` (deprecated) * `tornado.netutil.ThreadedResolver` (deprecated) * `tornado.netutil.OverrideResolver` * `tornado.platform.twisted.TwistedResolver` (deprecated) * `tornado.platform.caresresolver.CaresResolver` (deprecated) .. versionchanged:: 5.0 The default implementation has changed from `BlockingResolver` to `DefaultExecutorResolver`. .. versionchanged:: 6.2 The default implementation has changed from `DefaultExecutorResolver` to `DefaultLoopResolver`. r c C � t S �N)r� ��clsr r r! �configurable_baseW � zResolver.configurable_basec C r� r� )�DefaultLoopResolverr� r r r! �configurable_default[ r� z Resolver.configurable_defaultrY r r c C s t � �)a Resolves an address. The ``host`` argument is a string which may be a hostname or a literal IP address.

If a ``callback`` is passed, it will be run with the result as an argument when it is complete. :raises IOError: if the address cannot be resolved. .. versionchanged:: 4.4 Standardized all implementations to raise `IOError`. .. versionchanged:: 6.0 The ``callback`` argument was removed.
