IP addresses are divided into different classes depending on network size and intended use.
Class A IP addresses are designed for very large networks. These are addresses whose first octet is between 1-126 .
Class B IP addresses are designed for medium-sized networks. These are addresses whose first octet is between 128-191 .
Class C IP addresses are designed for small networks. These are addresses whose first octet is between 192-223 . It is the most commonly used IP class.
Class D (224-239): It is used for multicast transmission. It allows sending packets to multiple hosts.
Class E (240-255): Reserved for future use and experimental purposes. Commercial use is not supported.
The IP classification system (classful addressing) has now been largely replaced by the CIDR (Classless Inter-Domain Routing) method. CIDR allows more flexible allocation of IP address blocks and is specified with prefix lengths such as "/24". However, IP classes are still important to network fundamentals and historical context, and these classes are widely referenced by network technicians.
