An IP address that is permanently assigned to a device is called a:

• A. Dynamic IP
• B. Static IP
• C. Private IP
• D. Public IP

Answer: (B)

Permanent addressing in IP networks is called a static IP. This means the device keeps the same address over time, ensuring reliable reachability for services that rely on a fixed location, like servers or printers. Static addresses can be used inside private networks or assigned publicly by an ISP, but the defining trait is that the address does not change. In contrast, dynamic IPs are handed out by methods like DHCP and can change when the device reconnects or after a lease expires. Private versus public describes whether the address is routable on the internet or limited to a local network, not whether it’s fixed or variable. So the term that matches a permanently assigned address is static IP.
