The Dynamic Host Configuration Protocol (DHCP) is an auto configuration protocol used on IP networks.

The Dynamic Host Configuration Protocol (DHCP) is an auto configuration protocol used on IP networks and an extension of the Bootstrap Protocol.

DHCP allows for computers to be configured automatically to communicate with each other over an IP network without the need for setup by a network administrator.

It keeps track of the computers connected to the network with a central database and prevents two computers from accidentally being configured with the same IP address.
