The invention relates to a communication module for connecting a lighting bus system (1) to a network (3) based on an internet protocol, wherein each component (2a . . . 2f) coupled to the bus system (1) is assigned a unique bus address, the communication module (4) is assigned a plurality of network addresses, at least one of the plurality of network addresses contains the bus address of a component (2a . . . 2f) and the communication module (4) is designed to receive data transmitted to the at least one network address from the network (3), to extract the bus address of the component (2a . . . 2f) from the network address, to determine data to be transmitted to the component (2a . . . 2f) by using the extracted bus address on the basis of the received data, and to transmit the determined data to the component (2a . . . 2f) having the extracted bus address via the bus system (1), or to provide the data generated autonomously by a component (2a . . . 2f) and transmitted to the communication module (4) to at least one network subscriber via the network (3).
