A multicast address is a logical identifier for a group of hosts in a computer network that are available to process datagrams or frames intended to be multicast for a designated network service.

Address assignments are listed below. The range of addresses between 224.0.0.0 and 224.0.0.255, inclusive, is reserved for the use of routing protocols and other low-level topology discovery or maintenance protocols, such as gateway discovery and group membership reporting.

This lesson provides an overview of the different 224.0.x.x multicast address ranges and their functions in networking.

2024年12月17日 · Any IP address within this range is used for multicast communication. Devices or hosts wishing to communicate with a multicast group must join the specific address in this range. This range is distinct from other address classes like: Class A (1.0.0.0 - 127.255.255.255): [Unicast addresses]

So, the full range of multicast addresses is from 224.0.0.0 to 239.255.255.255. Since multicast addresses represent a group of IP devices (sometimes called a host group ) they can only be used as the destination of a datagram; never the source.

The multicast routing is specific and broad range of protocols for layer-3 routing protocol for multicast feature and it is defined in RFC 5110. [5] ... There are four types of Well-Known IPv6 Multicast address range : ff02::1: All IPv6 devices,•ff02::2: All IPv6 routers,•ff02::5: All OSPFv3 routers,•ff02::a: All EIGRP (IPv6) routers.

The range of addresses between 224.0.0.0 and 224.0.0.255, inclusive, is reserved for the use of routing protocols and other low-level topology discovery or maintenance protocols, such as gateway discovery and group membership reporting. Multicast routers should not forward

A multicast address that includes a group and source IP address is often referred to as a channel. The Internet Assigned Number Authority (IANA) has assigned 224.0.0.0 through 239.255.255.255 as IPv4 multicast addresses.

The multicast address scope ranges from 224.0.0.0 to 239.255.255.255. In the multicast address range, multiple blocks of addresses are reserved for specific purposes which include the following: Designation
