Detailed Description
Configurable asynchronous DNS resolver interface.
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.BlockingResolver`
* `tornado.netutil.ThreadedResolver`
* `tornado.netutil.OverrideResolver`
* `tornado.platform.twisted.TwistedResolver`
* `tornado.platform.caresresolver.CaresResolver`

| ) |
Resolves an address. The ``host`` argument is a string which may be a hostname or a literal IP address. Returns a `.Future` whose result is a list of (family, address) pairs, where address is a tuple suitable to pass to `socket.connect <socket.socket.connect>` (i.e. a ``(host, port)`` pair for IPv4; additional fields may be present for IPv6). If a ``callback`` is passed, it will be run with the result as an argument when it is complete.
