The solution to the problem described in the question is DHCP reservation, which allows a specific IP address to be assigned to a device every time it connects to the network without violating the corporate policy of not using static IP addresses.
DHCP (Dynamic Host Configuration Protocol) is a network protocol used to automatically assign IP addresses and other network configuration parameters, such as default gateway and DNS servers, to devices on a network. DHCP allows for efficient management of IP addresses by avoiding conflicts and providing dynamic addressing.
DHCP relay (option A) is a technique used to forward DHCP messages across different network segments, allowing devices on remote subnets to obtain IP addresses from a DHCP server located on a different subnet. DHCP exclusion (option B) is a configuration option that specifies a range of IP addresses that should not be assigned by the DHCP server, often used to reserve specific IP addresses for devices with static IP addresses. DHCP option (option C) is a configurable parameter that can be used to provide additional information to DHCP clients, such as domain name or time server information.
In contrast, DHCP reservation (option D) allows a specific IP address to be assigned to a device based on its MAC address. The MAC address is a unique identifier assigned to each network interface card (NIC) and is used by the DHCP server to identify the device and assign the reserved IP address. DHCP reservation ensures that the device always receives the same IP address every time it connects to the network without the need for static IP addresses.
In summary, DHCP reservation is the best option to fulfill the request described in the question while adhering to the corporate policy of not using static IP addresses.
