Your home network relies on two invisible systems working together: IP addresses that identify each device on your network, and DNS that translates website names into the addresses your devices actually need. Understanding how these work helps you troubleshoot connection problems, recognize when something's wrong, and make better decisions about your network's security and privacy.
The articles here explain what IP addresses do, how DNS queries work, why your router assigns addresses the way it does, and what happens when DNS stops working properly. You'll learn how to read network information on your devices, what different address types mean, and how to spot unusual activity on your network.
