Which devices typically require a static IP address rather than DHCP?

• A. Servers, network printers, file shares, and devices needing a consistent address
• B. Laptops assigned by DHCP only
• C. Home consumer devices
• D. All client desktops automatically

Answer: (A)

Static IP addresses are used for devices that act as services or anchors on a network. When a device runs a server, a network printer, or a file share, other devices and services rely on knowing exactly where to reach it. A fixed address ensures the device is found every time, DNS records stay correct, and access rules or port forwarding remain stable. If such a device obtained its address dynamically, the IP could change after a reboot or lease renewal, breaking connections and making resources inaccessible. In many networks you can still achieve the same effect with DHCP reservations—letting the DHCP server assign the same IP while still managing it centrally. Laptops, home consumer devices, and typical client desktops usually use DHCP because their addresses can change and they don’t provide persistent services that others must locate reliably.
