*Class-B Address Range in CIDR Notation*
The CIDR notation 128.0.0.0/2 represents the Class-B address range in a broader manner. In CIDR notation, the “/2” indicates that the network prefix length is 2 bits, meaning that the first 2 bits of the IP address are used to identify the network portion, while the remaining 30 bits are available for addressing individual hosts within the network.
For the Class-B address range, the CIDR notation is typically represented as 128.0.0.0/16. This notation indicates that the first 16 bits (the first two octets) of the IP address represent the network portion, while the remaining 16 bits (the last two octets) represent the host portion. The range for a Class-B network spans from 128.0.0.0 to 191.255.255.255.
The CIDR notation 128.0.0.0/2 includes a larger address range that covers both the Class-A and Class-B address ranges. It starts at 128.0.0.0 and extends up to 191.255.255.255, utilizing the first two bits of the first octet to determine the network portion.
