How to Answer
This is an example of a follow-up question. Interviewers use follow-up questions to dig deeper into a topic or ensure that you're consistent in your answers throughout the interview. If the follow-up question immediately follows a question about the same topic, they are exploring the topic in more detail. If it comes later in the interview, they are testing if you are consistent with your answers. In either case, keep your answers to the point and honest. this will not only inspire confidence from the interviewer, but will demonstrate your competency.
Answer Example
"No, the IP address 127.0.0.1 is reserved for localhost connections. This IP address is used to troubleshoot the network and identify any hardware or connection issues. When trying to diagnose and resolve a network connectivity issue, the first step is to ping the server and check if it responds. You do this by typing 127.0.0.1 into your web browser. If there is no response from the server, then there may be several root causes for the problem. It may be that the network is down, or a cable has become disconnected, or the network card has a problem. If you can ping this server successfully it means that the hardware is in good shape and working properly."
