IP addressing operates at which OSI layer?

Explanation:
IP addressing is a function of the Network Layer, the third layer of the OSI model. This layer handles logical addressing and routing, enabling packets to be forwarded across multiple networks. IP addresses identify both the network and the host, guiding routers on where to send each packet toward its destination. In contrast, the Data Link Layer (Layer 2) uses MAC addresses for local delivery on a single network, and the Transport Layer (Layer 4) deals with ports and end-to-end communication, not addressing. So, IP addressing operates at the Network Layer (Layer 3).
