DNS (Domain Name System) translates website names like Google.com into IP addresses that computers can understand. When DNS stops working, your internet may appear connected, but websites won’t open.
Fortunately, most DNS issues can be fixed quickly with a few troubleshooting steps.
✅ Common Signs of DNS Problems
- “DNS Server Not Responding” error
- Websites won’t load
- Internet connected but no browsing
- Browser shows server not found
- Some websites work while others don’t
- Slow website loading
