What type of communication does the DHCP server to client typically use?

The Dynamic Host Configuration Protocol (DHCP) server typically uses broadcast communication to communicate with clients during the lease request and offer process. When a client device initially connects to a network and requests an IP address, it sends a broadcast message to ensure that the DHCP server can receive it, even if the client currently doesn't know the server's IP address. This broadcast, known as a DHCP Discover message, is sent to the network to reach all potential DHCP servers.

Upon receiving this Discover message, one or more DHCP servers respond with a DHCP Offer message, which is also broadcasted in certain cases. This ensures that all clients in the same network segment can hear the offer, allowing them to select and request an appropriate IP configuration. The broadcasting method is essential because, at the time of the communication, the client does not yet have an assigned IP address, so it cannot send unicast messages.

To summarize, broadcasting is fundamental to the DHCP communication process, particularly in the initial phases of address assignment, making it the correct choice for how DHCP servers communicate with clients.
