What protocol is used to assign dynamic IP addresses to devices on a network?

Dynamic Host Configuration Protocol (DHCP) is the correct choice for assigning dynamic IP addresses to devices on a network. This protocol enables network devices to request and receive IP addresses and other configuration parameters automatically. Using DHCP streamlines the process of managing IP addresses within a network by allowing devices to obtain these addresses as needed, rather than requiring manual configuration for each device. This not only saves time and effort but also helps to avoid the common problems associated with static IP address assignments, such as address conflicts.

In addition to providing IP addresses, DHCP can also deliver other critical network information, like the subnet mask, default gateway, and domain name system (DNS) server addresses, ensuring devices are set up correctly for communication within the network. When a device connects to the network, it sends a broadcast request for an IP address, and the DHCP server responds with an available address from its pool, making the process efficient and effective for dynamic network environments.
