What is DHCP? - Dynamic Host Configuration Protocol
The Dynamic Host Configuration Protocol or DHCP is a network management protocol used on UDP/IP networks whereby a DHCP server dynamically assigns an IP address and other network configuration parameters to each device on a network so they can communicate with other IP networks.
The protocol can be implemented of networks of any sizes, ranging from small home area networks (HAN) to large campus area networks (CAN) and even the networks used by Internet Service Providers (ISP).
A router or a residential gateway can be enabled to act as a Dynamic Host Configuration Protocol server. Most residential network routers receive a globally unique IP address within the ISP network. Within a local network, a DHCP server assigns a local IP address to each device connected to the network.
