WebA multicast IP address also has 32 bits, but the first 4 bits are always the same (1110) because we use the 224.0.0.0 – 239.255.255.255 range. This means that each multicast IP address has 28 unique bits. Now if we want to map our 28 bit multicast IP address to our 23 bit MAC address, we have a problem…we miss 5 bits of mapping information: WebDec 29, 2024 · For IPv4, the range of multicast MAC addresses is 01:00:5e:00:00:00 to 01:00:5e:7f:ff:ff. There are 28 bits of IPv4 multicast group addresses, but there are only 23 bits of MAC multicast addresses. That means that every multicast MAC address represents 32 different IPv4 multicast addresses ( 28 - 23 = 5 and 2^5 = 32 ).
