In a desktop environment, which devices commonly use static IP addresses?

• A. A typical desktop in home environment.
• B. A laptop moving between networks.
• C. An IoT device.
• D. A printer or server requiring fixed address.

Answer: (D)

Static addresses are most useful for devices that must be reached at a single, predictable address on the network. In a desktop environment, printers and servers provide shared services or resources (printing, file access, network services) that other computers need to locate reliably. If such a device were to rely on dynamic addressing, its address could change after a reboot or lease renewal, breaking connections and requiring reconfiguration of drivers, shortcuts, and access rules. Giving the device a fixed IP (or using a DHCP reservation tied to that device) ensures clients can always reach it at the same address. Desktops and laptops typically move between networks or end up with addresses assigned by DHCP, which is convenient for changing locations. IoT devices can also use fixed addresses, but in a desktop environment the common scenario for a fixed address is a printer or server that others depend on.
