Advantages of the Classful Design The primary advantage of the Class B system was its hierarchical efficiency for routing. Modern Context and Legacy.
Understanding the Class B IP Address Range and Its Structure
Instead of storing a path to every single device, a router could simply know the path to the network "128. This made it ideal for large universities, mid-sized corporations, and early internet service providers in the 1990s.
These inefficiencies contributed to the rapid exhaustion of the IPv4 address space. The main drawback was the potential for waste; if an organization needed more than 65,000 addresses, they had to request a Class A address, which could waste millions of unused IPs.
Understanding the Class B IP Address Range and Its Implications
Every device connected to a network requires a unique numerical label to communicate, and this label is defined by the Internet Protocol. With 16 bits available for host addresses, a single Class B network can theoretically support up to 65,534 individual devices (2^16 minus two addresses reserved for the network and broadcast identifiers).
