Which statement about static and dynamic IP addresses is true?

Which statement about static and dynamic IP addresses is true?

• A. Static IP addresses change automatically and are assigned by DHCP
• B. Dynamic IP addresses are fixed and require manual assignment
• C. Static IP addresses remain the same; dynamic IP addresses can change and are assigned by DHCP
• D. There is no difference between static and dynamic IP addresses

Answer: (C)

IP addresses can be fixed or change over time. A static IP address stays the same because it’s set manually on the device or reserved in the network’s router, ensuring the device always appears at the same address. A dynamic IP address is assigned automatically by DHCP (Dynamic Host Configuration Protocol) and can change when the device reconnects or when the lease on the address expires. That’s why the statement that static IP addresses remain the same and dynamic IP addresses can change and are assigned by DHCP is correct. The other descriptions mix up how static and dynamic addresses work—for example, static addresses aren’t typically assigned by DHCP and don’t change, while dynamic addresses aren’t fixed and are managed by DHCP. If you’re configuring devices, use static IPs for servers and printers that must be consistently reachable, and dynamic IPs for most workstations and mobile devices to simplify management.
