Which layer does DHCP typically operate at?

Dynamic Host Configuration Protocol (DHCP) operates at the application layer of the OSI model. This layer is responsible for providing network services to applications and enables protocols to manage communication sessions between endpoints. Specifically, DHCP is designed to automate the process of IP address assignment and configuration settings for devices on a network. It enables devices to request and obtain IP addresses and other network parameters, simplifying network administration and management.

The application layer encompasses protocols that facilitate software applications to interact with the underlying network, which is precisely what DHCP does. It uses protocols like UDP (User Datagram Protocol) at the transport layer to transmit its messages, but its core functionality and purpose align with the application layer. By operating here, DHCP communicates the necessary network information to clients without dealing directly with lower-layer functionalities like data transportation or network routing.
