DHCP dynamically allocates IP addresses and essential network settings—such as subnet mask, gateway, and DNS servers—to devices as they join a network. This automation eliminates manual configuration, reduces errors, and ensures efficient use of IP address space.

Operating using a client-server model, DHCP relies on centralized servers to manage address pools and lease durations. Security features such as DHCP snooping and authentication help prevent unauthorized access and address misuse. DHCP is scalable for networks of all sizes and supports dynamic DNS updates for seamless name resolution.

Widely used in enterprise, wireless, and ISP networks, DHCP is foundational for efficient network operations, enabling devices to connect and communicate reliably with minimal administrative overhead. In large-scale or automated environments, solutions like Hedgehog can integrate DHCP to further streamline device onboarding and network provisioning.
