Explanation

Layer 3, the Network layer, is responsible for logical addressing (IP addresses) and path determination. Routers operate at this layer, using IP addresses to make forwarding decisions and build routing tables. Layer 4 (Transport) handles end-to-end communication and segmentation (TCP/UDP). Layer 7 (Application) provides network services to user applications. Layer 6 (Presentation) handles data formatting, encryption, and translation. None of those layers deal with the logical addressing that enables routing between different networks.
