Abstract

An embodiment of the invention provides a method for solving an IP address conflict, electronic equipment and a computer. The method comprises the steps that after first electronic equipment receives a first IP address distributed by second electronic equipment for the first electronic equipment, the first IP address is set as a static IP address; and when the first electronic equipment monitors that a second IP address distributed by third electronic equipment for the first electronic equipment conflicts with the current static IP address, the second electronic equipment is informed to distribute a third IP address again for the first electronic equipment. The first electronic equipment informs the second electronic equipment to distribute the IP address again only when discovering that the IP address distributed by other electronic equipment for the first electronic equipment conflicts with the previous static IP address, so that the number of times for distributing the IP address for the first electronic equipment is reduced, the communication stability of a system where the two electronic equipment is located is enhanced, and the time required by communication handshake between the first electronic equipment and the second electronic equipment is shortened.
