Question

A says complete 48-bit MAC addresses are allocated to NIC manufactures from the IEEE. Buster says IEEE only assigns the first 24 bits to manufactures Carlos says the IEEE assigns only the last 2 bits to manufactures. Who is correct?

A. Only A is correct
B. Only Buster is correct
C. Only Carlos is correct
D. No one is correct

Answer 1

Buster is correct in saying that the IEEE assigns only the first 24 bits, known as the OUI, to manufacturers, which is used as a unique identifier for that company's network products. The remaining 24 bits are usually assigned by the manufacturers themselves.

Step-by-step explanation:

The question pertains to how the IEEE (Institute of Electrical and Electronics Engineers) assigns MAC addresses to network interface card (NIC) manufacturers. A Media Access Control (MAC) address is a unique identifier assigned to network interfaces for communications on the physical network segment.

In this case, Buster is correct. The IEEE assigns only the first 24 bits of the MAC address, known as the Organizationally Unique Identifier (OUI), to manufacturers. This OUI ensures that each manufacturer can generate a unique MAC address for their network devices, with the remaining 24 bits typically being assigned by the manufacturer to ensure the overall uniqueness of the full 48-bit MAC address. Thus, the correct answer to the question would be B. Only Buster is correct.
