How many bits are in an ethernet mac address
WebThis means we have to map multiple Multicast IP addresses to the same Multicast MAC address. We don’t have enough MAC addresses to give each multicast IP address its own MAC address. We miss 5 bits of mapping information: 2 5 = 32. This means we will map 32 multicast IP addresses to 1 multicast MAC address. Here’s an example: 224.1.1.1; 224 ... WebMay 16, 2012 · The MAC address is first separated into two 24-bits, with one being OUI (Organizationally Unique Identifier) and the other being NIC specific.
