Final answer:
A reserved IP address is a permanent IP address assignment from a DHCP server.
Step-by-step explanation:
The term used to describe a permanent IP address assignment from a DHCP server is Reserved IP.
A reserved IP address is one that is set aside for a specific device and is always assigned to that device by the DHCP server. It is not used by any other device on the network. This ensures that the device will always have the same IP address, even if it disconnects and reconnects to the network.
For example, if a printer has a reserved IP address of 192.168.1.10, it will always be assigned this IP address by the DHCP server and no other device on the network will be assigned the same IP address.
