2. Check your Wi-Fi connection: Ensure that your Chromebook is connected to a Wi-Fi network. Click on the Wi-Fi icon in the bottom right corner of the screen and select a network to connect to.

3. Clear your DNS cache: A corrupted DNS cache can cause the “DNS address not found” error. Press “Ctrl + Shift + T” to open the Chrome OS developer shell, then type the command “sudo rc-network-manager restart” and press enter. This will clear the DNS cache and restart the network manager.

4. Disable VPN or Proxy: If you are using a VPN or proxy service, try disabling it temporarily to see if it resolves the issue. Click on the Wi-Fi icon, then click on the name of your VPN or proxy service and select “Disconnect” or “Disable.”

5. Check your DNS settings: Ensure that your Chromebook is using the correct DNS settings. Click on the Wi-Fi icon, then click on the name of your Wi-Fi network and select “Network” or “Wi-Fi settings.” Scroll down and click on “Advanced,” then under “DNS,” select “Automatic” or enter a custom DNS server if required.

Flush DNS Cache for Improved Connectivity

To flush the DNS cache on your Chromebook and improve connectivity, follow these simple steps:

1. Open the Chrome browser.
2. Type “chrome://net-internals/#dns” in the address bar and press Enter.
3. Click on the “Clear host cache” button.
4. Close the Chrome browser and restart your Chromebook.

By flushing the DNS cache, you are clearing any stored information that could be causing connectivity issues. This allows your Chromebook to fetch fresh DNS information from the name servers, improving your connection to websites and online services.

Remember, the DNS (Domain Name System) is responsible for translating domain names into IP addresses, allowing your device to access the World Wide Web. Clearing the DNS cache can help resolve issues when a website’s address cannot be found.

If you are using a virtual private network (VPN) or have recently changed your DNS settings, flushing the DNS cache can help ensure that your Chromebook is using the correct DNS information.

So, if you are experiencing “DNS address not found” errors on your Chromebook, try flushing the DNS cache following the steps mentioned above. This simple fix can often resolve connectivity issues and get you back online quickly.

Utilize VPN for Accessing Blocked Content

To access blocked content on your Chromebook, you can utilize a VPN (Virtual Private Network). A VPN allows you to connect to a private network over the internet, masking your IP address and encrypting your connection for enhanced privacy and security. Here’s how you can use a VPN to fix the “DNS address not found” issue on your Chromebook:

1. Choose a reliable VPN service: Look for a reputable VPN provider like Proton VPN that offers a user-friendly interface and strong encryption protocols.

2. Install the VPN app: Visit the Chrome Web Store and search for the VPN app of your choice. Install the app and follow the setup instructions.

3. Connect to a VPN server: Open the VPN app and choose a server location from the available options. This will assign you a new IP address and establish a secure connection.

4. Test your connection: Once connected, open your Chrome browser and visit a website that was previously blocked. If the “DNS address not found” error persists, try clearing your browser cache or switching to a different VPN server.

Remember, using a VPN may slightly affect your internet speed due to the encryption process. However, the benefits of accessing blocked content and protecting your online privacy outweigh the potential slowdown.

Reconfigure or Reinstall Chrome for Optimal Performance

To fix the “DNS Address Not Found” issue on your Chromebook, you can either reconfigure or reinstall Chrome.

Reconfiguring Chrome is a simple process that can help improve its performance. First, open Chrome and click on the three vertical dots in the top-right corner.

Under the “Privacy and security” section, click on “Clear browsing data.” Make sure to select “Cached images and files” and “Cookies and other site data.” Click on “Clear data” to remove these files from your browser’s cache.

If reconfiguring doesn’t resolve the issue, you can reinstall Chrome on your Chromebook. To do this, open the Chromebook’s app launcher and find the Chrome browser. Right-click on the Chrome icon and select “Uninstall.” Confirm the uninstallation. Once uninstalled, go to the Chrome Web Store and search for “Chrome.” Install the browser again by clicking on “Add to Chrome.”
