While IP addresses can be dynamically assigned by DHCP, the _______ address is hard-coded into a device's NIC.
- DNS
- Host
- MAC
- Subnet
The correct answer is "MAC" (Media Access Control) address. The MAC address is a unique hardware address assigned to a network interface controller (NIC) at the time of manufacturing. It is used for identifying devices on a physical network. Unlike IP addresses, which can change dynamically, MAC addresses are permanent and tied to the device.
