Which IP address type can change when you reboot your ISP device?

• A. Static
• B. Dynamic
• C. DNS
• D. Public

Answer: (B)

This question tests how IP addresses are assigned and how they can change. Dynamic IP addressing is provided by the network’s DHCP server (usually the ISP’s device). When you reboot your ISP router, the device drops and renews its lease from the DHCP server, and the server may assign a different address if available. That’s why the public-facing IP can change after a reboot. Static IP addresses are manually assigned and stay the same unless you reconfigure them, so they don’t routinely change on reboot. DNS refers to the system that translates domain names to IP addresses, not the nature of the IP address itself. Public describes the scope of the IP (reachable on the internet) and doesn’t by itself define whether it changes on reboot.
