Explanation
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 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. 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.
