Which technology enables the assignment of dynamic IP addresses in networks?

Dynamic Host Configuration Protocol (DHCP) is the technology that enables the assignment of dynamic IP addresses in networks. It automates the process of assigning IP addresses to devices within a network, allowing them to join and communicate without manual configuration. When a device connects to the network, DHCP assigns it an available IP address from a predefined range, which can change each time the device reconnects.

This dynamic allocation is crucial in environments with many devices, such as in businesses or home networks, where the number of devices may change frequently. By using DHCP, network administrators can efficiently manage IP address distribution, reducing conflicts and ensuring that devices have the necessary configuration to communicate effectively on the network.

Other options, such as Network Address Translation (NAT), primarily deal with modifying IP address information in transit and enabling devices on a local network to connect to the internet using a single public IP address. Static Assignment Protocol (SAP) isn't a recognized standard for IP address assignment, and IPv6 refers to a version of the Internet Protocol, not specifically to the process of dynamically assigning IP addresses like DHCP does.
