Then the methodology, including the data collection method, data format, and the definition of highly active IP prefixes, is given.

It uses three pieces of DDR II to store IP forwarding table corresponding to the IP address prefixes whose characteristics have been exploited.

Through the server in allocation center and the tobacco sale terminal device inserted in GSM communication module as well as by using of data communication technique combined with GPRS/SMS,the bidirectional data transmission of tobacco sale terminals with dynamic IP address is completed,and finally the informationized administr.

The research on risk situation forecast of IP address dynamic distribution system in logistics information system networks in this paper is anapplication of network security situation awareness in reality.
