Instantiate a NBNSProtocol instance.
This automatically calls reactor.listenUDP method to start listening for incoming packets, so you **must not** call the listenUDP method again.
:param boolean broadcast: A boolean flag to indicate if we should setup the listening UDP port in broadcast mode
:param integer listen_port: Specifies the UDP port number to bind to for listening. If zero, OS will automatically select a free port number.

Send a query on the network and hopes that if machine matching the *name* will reply with its IP address.
:param string ip: If the NBNSProtocol instance was instianted with broadcast=True, then this parameter can be an empty string. We will leave it to the OS to determine an appropriate broadcast address.
If the NBNSProtocol instance was instianted with broadcast=False, then you should provide a target IP to send the query.
:param integer port: The NetBIOS-NS port (IANA standard defines this port to be 137). You should not touch this parameter unless you know what you are doing.
:param integer/float timeout: Number of seconds to wait for a reply, after which the returned Deferred instance will be called with a NetBIOSTimeout exception.
:return: A *twisted.internet.defer.Deferred* instance. The callback function will be called with a list of IP addresses in dotted notation (aaa.bbb.ccc.ddd).
On timeout, the errback function will be called with a Failure instance wrapping around a NetBIOSTimeout exception

Send a query to the machine with *ip* and hopes that the machine will reply back with its name.
The implementation of this function is contributed by Jason Anderson.
:param string ip: If the NBNSProtocol instance was instianted with broadcast=True, then this parameter can be an empty string. We will leave it to the OS to determine an appropriate broadcast address.
If the NBNSProtocol instance was instianted with broadcast=False, then you should provide a target IP to send the query.
:param integer port: The NetBIOS-NS port (IANA standard defines this port to be 137). You should not touch this parameter unless you know what you are doing.
:param integer/float timeout: Number of seconds to wait for a reply, after which the method will return None
:return: A *twisted.internet.defer.Deferred* instance. The callback function will be called with a list of names of the machine at *ip*.
On timeout, the errback function will be called with a Failure instance wrapping around a NetBIOSTimeout exception
