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 ...
WebEach MAC address is unique to the network card installed on a device, but the number of device-identifying bits is limited, which means manufacturers do reuse them. Each manufacturer has about 1.68 million available addresses, so when it burns a device with a MAC address ending in FF-FF-FF, it starts again at 00-00-00.
