What is a dynamic IP address assigned by?

A dynamic IP address is assigned by a DHCP server, which stands for Dynamic Host Configuration Protocol. This server automatically assigns IP addresses to devices on a network. When a device connects to the network, it sends a request for an IP address, and the DHCP server responds by providing an available address from a predefined pool. This process simplifies network management, allowing for easier configuration and reconfiguration of devices without the need for administrative intervention for each connection.

In contrast, static configuration would involve manually setting an IP address on a device, which does not fall under the jurisdiction of a DHCP server. A router may facilitate DHCP functionality by acting as the DHCP server or forwarding DHCP packets, but it is not the entity that assigns dynamic IP addresses directly. Manual entry refers to a situation where a user inputs an IP address without any automation, and thus, it is also not related to dynamic assignment.
