IP address classes

IP address classes categorize range types for different network sizes. Class A addresses (1.0.0.0 to 126.255.255.255) are used for large networks like big companies, supporting many devices. Class B (128.0.0.0 to 191.255.255.255) is suited for medium-sized networks, like universities. Class C (192.0.0.0 to 223.255.255.255) fits smaller networks, such as small businesses. Class D (224.0.0.0 to 239.255.255.255) is for group communication (multicast), and Class E (240.0.0.0 to 255.255.255.255) is reserved for experimental use. These classes help organize IP addresses based on network needs.
