What class of IP addresses is designated for small networks?

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

Answer: (C)

Class C IP addresses are specifically designated for small networks. This class provides a more limited IP address range compared to Class A and Class B, which are intended for larger networks. Class C addresses begin with a binary prefix of 110, allowing for 256 possible networks, each with up to 254 usable host addresses (the first and last addresses in the range are reserved for network and broadcast addresses, respectively).

This structure makes Class C ideal for small to medium-sized organizations that do not require the vast network potential of Classes A or B. The more modest address space allows these organizations to efficiently manage their network resources without the excess allocation that comes with larger classes.

In contrast, Class D is not used for standard networks but is designated for multicast groups, further distinguishing its purpose from that of Class C. This makes Class C the most suitable choice for small networks due to its balance of sufficient addresses and manageable network configuration.
