Dealing with DNS issues can be frustrating, especially if you’re new to Linux. DNS is critical because it translates domain names like www.example.com into IP addresses that computers can understand. When DNS doesn’t work correctly, websites may not load, and you may have trouble accessing network resources. This guide will walk you through some common DNS issues in Linux and how to troubleshoot them effectively.
