DHCP

The Dynamic Host Configuration Protocol (DHCP) is a computer networking protocol used by hosts (DHCP clients) to retrieve IP address assignments and other configuration information.

DHCP uses a client-server architecture. The client sends a broadcast request for configuration information. The DHCP server receives the request and responds with configuration information from its configuration database.
In the absence of DHCP, all hosts on a network must be manually configured individually - a time-consuming and error-prone undertaking.
