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. 0, providing a balance between network and host capacity with roughly 65,000 possible networks, each capable of supporting up to 65,000 hosts.
Understanding IP Classes Ranges and the First Octet Rule
The default subnet mask is 255. 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.
Class A: The Giants of Networking Class A addresses are the largest blocks of IP space, reserved for massive networks such as those used by internet service providers and very large enterprises. The default subnet mask for this class is 255.

7 million hosts per network. The first octet ranges from 192 to 223, with a default subnet mask of 255.
