What IP address class is used for large networks with many devices?

• A. Class A
• B. Class B
• C. Class C
• D. Class D

Answer: (A)

Class A IP addresses are designed for large networks that require a significant number of host addresses. This class supports a vast number of hosts under a single network because it utilizes a larger portion of the address space for host identification. The Class A address range starts from 0.0.0.0 to 127.255.255.255, allowing for over 16 million individual addresses in a single Class A network. In practical terms, organizations like major corporations or Internet Service Providers (ISPs) typically use Class A addresses to support a large number of devices within their networks, ensuring that they can accommodate growth and a high demand for IP addresses. The implication of this capability is noteworthy; as businesses expand and the number of devices connected to networks increases, the ability to manage and address a large quantity of devices becomes essential. Other classes, such as Class B and Class C, are suitable for medium and smaller networks, respectively, offering fewer available addresses than Class A. Class D is special in that it is reserved for multicast groups, not for standard addressing of hosts in a network. Thus, Class A is the appropriate choice for networks that require extensive hosting capabilities.
