A method of communication in LAN without setting IP is provided, especially for LAN with a host device and at least a peripheral device. The method includes: (1) the host device sending the peripheral device a broadcast search packet through LAN, (2) the peripheral device establishing a new routing table according to the packet, (3) the peripheral device returning a response packet containing IP data to the host device, (4) the host device establishing a new routing table according to the response packets returned from peripheral device, and (5) the host device performing wired or wireless LAN communication with peripheral device according to the new routing table. Therefore, the host device and the device can automatically detect IP data even they may belong to different sub-net to achieve the communication in LAN without setting IP.
