MAC (Media Access Control) addresses are 48-bit identifiers assigned to network interfaces for communication on a local network.
* Allocation of MAC Addresses :
* MAC addresses are not allocated by the IETF . Instead, they are managed and assigned by the IEEE (Institute of Electrical and Electronics Engineers) .
* The IEEE assigns blocks of MAC addresses to hardware manufacturers (vendors), who then assign unique MAC addresses to their devices.
* Structure of MAC Addresses :
* The first 24 bits (Organizationally Unique Identifier, OUI) identify the manufacturer.
* The remaining 24 bits are assigned by the manufacturer to ensure global uniqueness.
* Why FALSE?
* The statement incorrectly attributes the allocation of MAC addresses to the IETF, which is responsible for Internet standards like TCP/IP, not MAC address allocation.
Thus, the correct answer is FALSE .
