A client device on an Ethernet segment needs an IP address. If a DHCP server with the IP address 192.168.1.1 is enabled, how will the client obtain a usable IP?

• A. Send a DHCPREQUEST message
• B. Send a DHCPDISCOVER message to physical address FF-FF-FF-FF-FF-FF
• C. Send a DHCPOFFER message to the server
• D. Static assignment from the DHCP server

Answer: (B)

The appropriate way for a client device on an Ethernet segment to obtain an IP address from a DHCP server is by initially sending a DHCPDISCOVER message. This message is a broadcast sent to the MAC address FF-FF-FF-FF-FF-FF, which represents all devices on the local network segment. By broadcasting this message, the client is indicating to all DHCP servers on the network that it is seeking an IP address. When the DHCP server receives this DHCPDISCOVER message, it responds with a DHCPOFFER message, proposing an IP address and other configuration parameters for the client device. The process continues with the client then sending a DHCPREQUEST message to accept the offered address, followed by the DHCP server acknowledging the lease with a DHCPACK message. In this sequence, the initial broadcast of the DHCPDISCOVER message is essential because it kicks off the communication with the DHCP server that will eventually provide the usable IP address. This step is critical for dynamic IP addressing in network environments, ensuring that clients can easily configure themselves via network services.
