Active IP address allocating method and system

Abstract

The invention discloses an active IP address distribution method and a system, which is characterized in that: data of user properties is stored in a server; a fixed IP address is correspondingly distributed to each user property; a client is connected with a network by a PPPOE; the server distributes temporary IP addresses and is connected with the client; then the server authenticates the user properties at the client, finds out the IP addresses corresponding to the user properties and gives the IP addresses to client equipment; finally the client cuts off the temporary connection with the server. The correspondence and binding of the user properties and the IP addresses are compulsorily carried out by the method and system of the invention, the server carries out uniform distribution and active administration of the IP addresses, which can solve the problems of the arbitrary changes of IP and MAC of users, random distribution of PPPOE service, user identity confirmation, and original address authentication, etc.; the position, management and control of the IP addresses, various extended management, user tracking and compulsory identity authentication can be conveniently realized.

Description

technical field [0001] The invention relates to an active IP address allocation method and system, belonging to the technical field of IP address allocation. Background technique [0002] In the prior art, there are mainly the following three methods for assigning IP addresses: [0003] Fixed IP mode - use IP address + MAC address binding [0004] DHCP method - use random allocation method [0005] PPPOE mode - use PPPOE dial-up mode [0006] The comparison of the three allocation methods is as follows: [0007] project Fixed IP DHCP PPPOE address allocation fixed randomly Dial to obtain to bind IP+MAC can't can't user modification free randomly system IP conflict happen anytime Won't Won't system conflict happen anytime happen anytime Won't bandwidth loss Won't Won't 40% loss agreement TCP / IP DHCP PPPOE ...

AI Technical Summary

Problems solved by technology

[0008] It can be seen from the above table that there are some problems in the existing IP address allocation methods: such as the problem of users changing IP and MAC at will; DHCP service conflicts and random allocation problems and the inability to guarantee complete acquisition and allocation; PPPOE service efficiency issues and random allocation problems ;Identity confirmation and source address authentication issues, etc.
