The Dynamic Host Configuration Protocol (DHCP) is a network management protocol for Internet Protocol (IP) networks that uses a client–server architecture to assign IP addresses and other communication characteristics to devices connected to the network. The technology, which consists of two network components, a centrally placed network DHCP server and client instances of the protocol stack on each computer or device, eliminates the necessity for manually configuring network devices. When a client first connects to the network, it uses the DHCP protocol to request a set of parameters from the DHCP server.
