The invention discloses a method of automatically distributing network addresses for cascaded devices based on link layer data communication. The method comprises steps: a target mac address and a special target mac address are acquired; a plaintext check code and a link layer check code are acquired; a network address is deleted or marked in a data frame in the link layer; the number of remaining network addresses is calculated; and packaging on the data frame in the link layer is carried out. By adopting the above technology, a static network address distributed for each cascaded device can be ensured not to conflict, any manual processing is not needed, the specific physical location of the device can be determined and acquired through the network address, and control on a specific device at a certain position through the network address is extremely convenient and determined; the method can be adopted independently and can also be wholly integrated to other methods or separately integrated to other method
