*Class-D Address Range in CIDR Notation*
The CIDR notation 224.0.0.0/4 represents the Class-D address range in IPv4. The Class-D address range is specifically reserved for multicast IP addresses.
In CIDR notation, the “/4” indicates that the network prefix length is 4 bits, meaning that the first 4 bits of the IP address are used to identify the network portion, while the remaining 28 bits are available for addressing individual hosts within the network.
The Class-D address range spans from 224.0.0.0 to 239.255.255.255. These addresses are reserved for multicast group communication, where a single packet can be sent to multiple recipients simultaneously. Multicast addresses are used for various purposes, such as multimedia streaming, real-time communication, and network protocols like Internet Group Management Protocol (IGMP).
The CIDR notation 224.0.0.0/4 encompasses all the multicast IP addresses in the Class-D range. It indicates that the first 4 bits of the IP address are used to identify multicast groups, while the remaining 28 bits are available to define specific multicast groups within the range.
