Which layer of the OSI reference model is responsible for logical addressing and routing?

The Network layer (Layer 3) of the OSI reference model is responsible for logical addressing and routing. This layer provides the functional and procedural means of transferring variable-length data sequences from a source to a destination via one or more networks while maintaining the quality of service requested by the Transport layer. Logical addressing is implemented using IP addresses, and routing determines the best path for data to travel across the network.
