Which of the following describes the role of DHCP in networking?

The role of DHCP (Dynamic Host Configuration Protocol) in networking is primarily to assign IP addresses dynamically to devices within a network. When a device—like a computer, smartphone, or IoT device—connects to a network, DHCP automates the assignment of an IP address, subnet mask, default gateway, and other pertinent configuration settings that are necessary for the device to communicate effectively on that network. This eliminates the need for a network administrator to manually configure each device, making network management more efficient and reducing the potential for IP address conflicts.

DHCP operates through a client-server model where the DHCP server maintains a pool of available IP addresses and leases them to clients as they join the network. This dynamic assignment is particularly beneficial in environments where devices frequently connect and disconnect, allowing for seamless connectivity and optimal use of limited IP address resources.
