WebMulticasting on a LAN is a good place to start an investigation of multicasting at Layer 2. At Layer 2, multicast deals with media access control (MAC) frames and addresses instead of IPv4 or IPv6 packets and addresses. Consider a single LAN, without routing devices, with a multicast source sending to a certain group. WebNov 17, 2024 · The range of IPv4 multicast addresses is 224.0.0.0 to 239.257.257.257. The range of IPv6 multicast addresses begins with ff00::/8. Because a multicast address represents a group of addresses (sometimes called a host group), it can only be used as the destination of a packet. The source is always a unicast address.

WebThis is because there is a multicast address that serves the same purpose of broadcast which is ff02::1. This also exists for IPv4 in the form of 224.0.0.1, but for some reason (I'm guessing historical) IPv4 also has broadcasts. IPv6 decided to just get rid of broadcast since that multicast address does the same thing. WebJun 28, 2024 · An IPv4 multicast address has 28 bits of addressing ( 224.0.0.0/4, so 32-4=28 ). You must somehow map the 28 bits of IPv4 addressing into 23 bits of MAC addressing. That means there are 32 times ( 28-23=5 and 2^5=32) as many IPv4 multicast addresses as there are 48-bit MAC multicast addresses. WebOct 3, 2024 · IPv6 multicast addresses use the prefix ff00::/8, shown in Table 4-10, which is equivalent to the IPv4 multicast address 224.0.0.0/4.

WebIPv4 addresses are expressed as a set of four numbers in decimal format, and each set is separated by a dot. Thus, the term ‘dotted decimal format.’ Each set is called an ‘octet’ because a set is composed of 8 bits. The figure below shows the binary format of each octet in the 192.168.10.100 IP address: A number in an octet can range from 0 to 255. WebRFC 5771 IPv4 Multicast Guidelines March 2010 The first /24 in this range, 233.252.0.0/24, is assigned as "MCAST- TEST-NET" for use in documentation and example code. 233.252.0.0/24 SHOULD be used in conjunction with the [ RFC2606] domain names example.com or example.net in vendor and protocol documentation.

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 ).

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:
