Abstract: A method for avoiding the IP address conflict includes the following steps. First, once the router obtains an IP address as its WAN IP address, the network bits of the WAN IP address and the network bits of an IP pool of the router are retrieved. Then, it follows to determine whether the network bits of the WAN IP address is identical to that of the IP pool, and if yes, modify the network bits of the IP pool together with a LAN IP address of the router to be different from that of the WAN IP address. After that, an instruction is transmitted to the client terminals associated with the router. Upon reception of the instruction, the client terminals replace the old IP addresses with the new IP addresses assigned from the router in accordance with Dynamic Host Configuration Protocol.
