DHCP (Dynamic Host Configuration Protocol) is a network protocol that automatically assigns IP addresses and other network configuration parameters to devices on a network. It simplifies network management by reducing manual configuration.

• Helps devices quickly connect to the network without manual setup.

How DHCP Works

• Device sends a DHCP Discover request.
