- In general, multicast addresses in the range of 224.0.0.0 to 239.255.255.255 are reserved for use with multicast communication, and they are not routable in the traditional sense. These addresses are used to identify a group of hosts that should receive the same packet, rather than a specific individual host.
The range of multicast addresses from 225.0.0.0 to 231.255.255.255 is reserved for use with administrative scoping, which allows administrators to define multicast groups that are only visible within a particular administrative domain or network segment.
The range of multicast addresses from 235.0.0.0 to 238.255.255.255 is reserved for use with source-specific multicast (SSM), which allows a sender to specify the source of a multicast stream, enabling receivers to filter multicast traffic based on the source.
In both of these cases, multicast packets are typically forwarded by multicast routers using Internet Group Management Protocol (IGMP) or Multicast Listener Discovery (MLD) rather than traditional routing protocols.
