What is the primary function of the DHCP protocol?

The primary function of the DHCP protocol is to assign IP address information dynamically. DHCP, which stands for Dynamic Host Configuration Protocol, is used in networks to automatically assign IP addresses and other configuration parameters to devices (like computers, printers, and smartphones) when they join the network. This dynamic allocation is efficient because it reduces the possibility of IP address conflicts, as the DHCP server manages the pool of IP addresses and assigns them as needed, ensuring that each device gets a unique address for the duration of its connection. This process simplifies network management, especially in environments where devices frequently connect and disconnect.

Other options relate to different networking functions that are not the main purpose of DHCP. For example, transmitting data securely over the internet typically involves protocols like HTTPS or VPN, while resolving domain names refers to the role of the Domain Name System (DNS). Finally, synchronizing network device clocks is the role of the Network Time Protocol (NTP), not DHCP.
