What address identifies a device's location on an IP-based network?

• A. IP address
• B. MAC address
• C. URL
• D. Port number

Answer: (A)

In an IP-based network, the address that pins down where to deliver data is the IP address. Routers use this number to forward packets from one network to another, guiding traffic to the correct device across many networks. This address represents the device’s logical location within the network's structure, not its physical hardware. The MAC address is a hardware identifier tied to a network interface and doesn’t get routed across networks. A URL is a human-friendly location that, after translation (DNS), maps to an IP address but is about locating a resource rather than the device itself. A port number indicates a specific service on that device, not where the device sits in the network. So the IP address is the identifier of a device’s location on an IP-based network.
