Which type of IP Address is automatically assigned to network devices using a DHCP server?

Dynamic IP Addresses are assigned automatically to devices on a network by a DHCP (Dynamic Host Configuration Protocol) server. This process simplifies the management of IP addressing within a network by allowing devices to request an IP address when they connect. The DHCP server maintains a pool of available IP addresses and leases them to devices for a specific period.

When a device joins the network, it sends a request to the DHCP server, which responds with a dynamic IP address. This address can change when the device reconnects or after the lease time expires, making it efficient for managing a large number of devices without requiring manual configuration.

In contrast, static IP addresses are manually assigned and do not change, reserved IP addresses are set aside for specific devices, and public IP addresses are used for accessibility over the internet. Therefore, in the context of automatic assignment by a DHCP server, the dynamic IP address is the most accurate answer.
