DUID

DUID stands for DHCP Unique Identifier, which is a specialized identifier used by devices to uniquely identify themselves when requesting network configurations from a DHCP server. It helps the server recognize and provide consistent network settings to the same device across different sessions or networks. Think of it as a digital fingerprint for a device, ensuring that network assignments like IP addresses are managed accurately and efficiently. DUIDs are especially useful in IPv6 networks, where they replace older methods of device identification. They help maintain seamless connectivity and network management.
