Method for exchanging internet address

The invention discloses an internet address changing method, belonging to the computer network technical field. The method is characterized in that based on a present internet protocol, internet users are divided into massive common users and a plurality of groups of high performance users. The common users use the current internet service mode of doing the best, and the high performance users are configured with high performance addresses when in need and use high quality services. By the access control, the dynamic distribution, the routing release and the bandwidth reservation of the high performance addresses in an autonomous domain, the link selection and the bandwidth reservation among domains and the charging by time, the method can provide different services to different users. With perfect expansibility and stability, the internet address changing method effectively solves important problems of the current internet which comprise the service quality (QoS) problem, the networksafety problem, the sustainable development economic model, etc. And the internet address changing method provides a new architecture support for the development of wireless technology, multicast technology, and the like, of the current internet and other important technical fields.
