[Operating AV Systems] While troubleshooting a DSP, the AV technician notices that the DHCP server has failed due to the control system not being…

The Media Access Control (MAC) address is a unique identifier assigned to a network interface

controller (NIC) for communications at the data link layer of a network segment. DHCP servers

use this permanent, hardware-level address to identify specific devices. To ensure a device like a

DSP always receives the same IP address, an administrator creates a DHCP reservation, which

maps the device's unique MAC address to a specific, desired IP address. This allows the control

system to reliably find and communicate with the DSP on the network.
