Method, system and equipment for Internet IP address classification and bandwidth prediction

The embodiment of the invention discloses a method for classifying Internet IP addresses and forecasting rate of a target node. The method is applied to any node in the network to classify IP address ranges, wherein each class comprises continuous IP address ranges and addresses in the class have approximate transmission rate for the node; and the method forecasts data download rate of the target node. The embodiment of the invention also discloses a device for classifying the Internet IP addresses and forecasting the rate of the target node. By using the embodiments, when a network application program needs to select from a plurality of communication nodes, the method can improve possibility of selecting the node with the maximal bandwidth and most guaranteed connection quality, so as to reduce blindness of the application program in network communication, and reduce load and consumption caused by communication blindness in a network.
