When a newly purchased laptop connects to a local area network using DHCP, what destination address does it use to request a dynamically assigned address?

• A. 192.168.1.1
• B. 0.0.0.0
• C. 255.255.255.255
• D. 169.254.0.0

Answer: (C)

When a newly purchased laptop connects to a local area network using Dynamic Host Configuration Protocol (DHCP), it requests a dynamically assigned IP address using the destination address 255.255.255.255. This address is known as a broadcast address, which means that the request is sent to all devices on the local network. In the DHCP process, when a device first connects to the network and does not have an IP address assigned, it cannot use a specific IP to communicate with a DHCP server. Instead, it sends out a broadcast message, which includes its request for an IP address. Using 255.255.255.255 allows the request to reach all devices in the same broadcast domain, including any configured DHCP servers that can respond to the request. This broadcast approach is essential because the laptop does not have an IP address yet; therefore, it cannot send a unicast message to a specific server. The DHCP server listens for these broadcast messages and, upon receiving this request, will offer an IP address to the laptop, completing the DHCP process.
