Which of the following can a DHCP server use for address allocation?

• A. Statically bound IP address with MAC address
• B. Allocated IP address in the DHCP Discover packet
• C. First available IP address in the DHCP pool
• D. Expired and conflicting IP addresses

Answer: (A)

A DHCP server utilizes statically bound IP addresses with MAC addresses for address allocation by creating a fixed mapping between a specific MAC address of a device and an assigned IP address. This approach ensures that whenever the device connects to the network, it consistently receives the same IP address. This method is ideal for devices that require a permanent IP, such as printers or servers, allowing network administrators to maintain a predictable IP scheme. In contrast, options related to transient IP address allocation, such as those that involve DHCP Discover packets or first available IPs, may not guarantee the same level of consistency as static binding. Expired or conflicting IP addresses are problematic because they can lead to network conflicts and connectivity issues, further emphasizing the reliability that static binding provides. Hence, using a statically bound IP address with MAC address allocation is a fundamental practice in DHCP configurations.
