Which of these options characterizes Class C addresses?

Class C addresses are defined by their range in the first octet, which specifically spans from 192 to 223. This classification is integral to understanding IP address organization as it allows for the segmentation of networks and the efficient allocation of IP addresses.

In Class C addresses, the first three octets define the network portion, while the last octet is used for host addresses within that network. This structure makes Class C addresses particularly useful for small to medium-sized networks, as they can accommodate up to 254 hosts on each network.

The ranges given in the incorrect options do not correspond to Class C addresses. For instance, Class A addresses range from 1 to 126, accommodating large networks, while Class B addresses span from 128 to 191, which serve medium-sized networks. The range for Class D, which includes multicast addresses, is from 224 to 239. Understanding the distinctions between these address classes is crucial for IP address management and network configuration.
