These rules define how addresses are divided into network identifiers and host identifiers, determining the scale and scope of a network segment. The Limitations and Evolution of Classful Addressing The classful addressing model suffered from a significant flaw known as address wastage.
IP Classes Ranges Explained Simply
The first octet of a Class A address ranges from 1 to 126, with the notable exception of 127, which is reserved for the loopback address used for internal testing. To combat this, Classless Inter-Domain Routing (CIDR) was introduced, allowing for variable-length subnet masking (VLSM) that broke free from the rigid class boundaries, enabling more efficient allocation of IP blocks based on actual need rather than predefined classes.
This system, known as classful networking, categorized addresses into five primary groups: Class A, Class B, Class C, Class D, and Class E. Every device that connects to a network relies on a unique numerical label to communicate, and this label, the Internet Protocol address, is structured according to specific hierarchical rules.

The default subnet mask for this class is 255. The default subnet mask is 255.
