What is the subnet for a class C network?

Interviewers ask about the subnet for a class C network to evaluate your technical knowledge and understanding of networking principles. This question reveals your familiarity with key concepts such as IP addressing, subnetting, and the practical implementation of network principles. Red flags include providing inaccurate answers or demonstrating a lack of foundational knowledge in networking.

A class C network typically has a default subnet mask of 255.255.255.0, which allows for 256 IP addresses (0-255). However, two addresses are reserved (network and broadcast), leaving 254 usable addresses. For example, in the subnet 192.168.1.0/24, the valid host range would be from 192.168.1.1 to 192.168.1.254. If asked, clearly explain your reasoning and demonstrate how you would apply subnetting in a practical scenario.
