Standard Group MAC Addresses are MAC addresses that have been allocated for use by standard protocols and consist of the following four sets of MAC Group Addresses: • IEEE 802.1D MAC Bridge Filtered MAC Group Addresses, • Standard MAC Group Addresses, • MAC Group Addresses used in ISO 9542, and • Token Ring LAN Functional Addresses.

Which is an example of assigning MAC addresses?

For example, the xyz company can assign the MAC addresses to its NICs in the incremental order. The following table extends this example and adds two more demo companies (ABC and JKL) in the example. It also shows MAC addresses of 5 NICs from each company. Thus, this procedure ensures that no two NICs use the same MAC address in the universe.
