If your DNS server becomes unreachable or misconfigured, your device loses the ability to translate domain names into IP addresses. Typing a website address like myipnow.net into your browser would fail, even though your internet connection itself is still working. You would see errors like server not found or this site can't be reached, since your device has no way to look up where that name actually points. Interestingly, the connection to the internet at large still functions during this time. If you know a website's exact IP address, you can still type that number directly into your browser and reach the site, bypassing DNS entirely. This is a useful way to confirm that a DNS problem, rather than a broader connection issue, is causing the trouble you're seeing.
