What is the correct sequence of message exchanges between a DHCP server and client for a connection request?

The sequence of message exchanges between a DHCP server and client during a connection request follows a defined process that is essential for dynamic IP address assignment. Initially, the client initiates the communication by broadcasting a DHCP Discover message. This message is sent to locate available DHCP servers within the network.

Upon receiving the DHCP Discover message, the DHCP server responds with a DHCP Offer message. This offer includes an available IP address, the network configuration parameters, and the lease duration.

Following the receipt of one or more offers, the client then selects one of the offers and responds with a DHCP Request message. This message indicates to the server that the client is accepting the offered IP address and wishes to proceed with the configuration.

Finally, the DHCP server acknowledges this request by sending a DHCP ACK message back to the client. This acknowledgment confirms the IP address assignment and provides any additional necessary configuration information.

This step-by-step process—starting with a Discover message, followed by an Offer from the server, then a Request from the client, and finally an ACK from the server—ensures that the client receives an appropriate and valid IP address, completing the DHCP handshake successfully.
