Every host on the network must have a unique IP address to communicate with other network hosts. Some hosts, such as servers and printers, have a hardcoded IP address since they don't want the IP address to change. However, the vast majority of hosts have a dynamically assigned IP address.

DHCP is a method that's used on a network to provide configuration information to hosts on a network. In addition to providing an IP address, most responses provide additional information. This information can include the Domain Name Service (DNS) server's IP address and Network Time Protocol (NTP), which provides the time service for the network.

DHCP lets you conserve IP addresses on a busy network. It also removes the need for the tedious and unnecessary hardcoding of individual IP addresses.

DHCP is a client-server model, where hosts request an IP address, and the server responds with an IP address that is leased for a period. The lease...
