How to Block Websites with OpenDNS on Home WiFi

Controlling access to certain websites on your home WiFi can improve productivity, safeguard children, or prevent access to unwanted content. Using OpenDNS, a free and reliable DNS service, makes this process straightforward without needing to configure individual devices. This guide walks you through setting up OpenDNS to block specific websites on your entire home network, ensuring consistent restrictions across all connected devices.

What You’ll Need

  • Access to your home router’s admin interface (username and password)
  • An active internet connection
  • OpenDNS account (free registration)

Step-by-Step

  1. Create an OpenDNS account: Visit OpenDNS and sign up for a free account. Choose the FamilyShield or Home plan based on your needs. After registration, verify your email.
  2. Configure your network’s DNS settings: Log into your router’s admin panel. Usually, this is done by entering 192.168.1.1 or 192.168.0.1 into your browser. Enter your admin username and password.
  3. Change DNS server addresses on your router: Locate the DNS settings, often under WAN, Internet, or Network sections. Replace existing DNS addresses with OpenDNS’s primary and secondary servers:
    • 208.67.222.222
    • 208.67.220.220
  4. Save settings and reboot the router: Apply the changes and restart your router to ensure new DNS settings take effect.
  5. Configure website blocking in your OpenDNS dashboard: Log in to your OpenDNS account. Navigate to the Settings for your network, then go to the ‘Web Content Filtering’ section. Select ‘Custom’ filtering mode.
  6. Add websites to block: In the block list, enter the domain names of websites you want to restrict, such as example.com. Save your settings.
  7. Test the setup: On a device connected to your WiFi, visit the blocked sites. You should see a block page indicating the site is restricted.

Common Mistakes

  • Not changing DNS settings on the router—devices may still use default DNS servers, bypassing OpenDNS filters.
  • Forgetting to save and reboot the router after DNS changes—this can prevent the new DNS settings from taking effect.
  • Blocking only specific devices instead of setting DNS at the router level—this leads to inconsistent filtering.
  • Entering incorrect domain names—misspellings or incomplete URLs can render blocking ineffective.
  • Not verifying the DNS configuration—using online tools like DNS Leak Test can confirm your DNS settings are correct.

Tips

  • Use OpenDNS’s ‘Dashboard’ to monitor and update your block lists as needed.
  • Combine DNS blocking with other parental controls or security software for layered protection.
  • Regularly review your block list to add or remove websites based on your needs.
  • Ensure your devices are configured to obtain DNS automatically from the network—manual DNS settings on devices can override router settings.
  • Clear your browser cache or restart devices after making DNS changes to ensure new settings are applied.

Troubleshooting

  • Blocked sites still accessible: Verify DNS settings on your router and ensure they point to OpenDNS servers. Clear browser cache and restart devices.
  • DNS leaks or bypass: Some devices may use alternative DNS servers. Use DNS leak test tools to confirm your network uses OpenDNS.
  • Blocking not working on mobile devices: Check if the device uses WiFi or cellular data; DNS settings on WiFi should be correct. For cellular, consider using parental controls on the device itself.
  • Changes not reflected immediately: Wait for DNS cache to expire or restart devices. You can also flush DNS cache manually on some systems.
  • Unable to access OpenDNS dashboard: Ensure you are logged into the correct account and that your network is properly registered.

Frequently Asked Questions

1. Can I block websites on all devices without installing software?

Yes. By configuring your router to use OpenDNS, all devices connected to your WiFi will be subject to the same filtering rules without installing additional software.

2. Is OpenDNS free to use for website blocking?

OpenDNS offers a free plan that includes basic filtering and blocking features suitable for most home users. There are premium options with more advanced features.

3. How long does it take for website blocks to activate?

Changes typically take effect within a few minutes, but clearing your browser cache or restarting devices can speed up the process.

4. Can I unblock a website temporarily?

Yes. Simply log into your OpenDNS dashboard and remove the website from your block list, then save changes. Remember to re-add it if needed later.

5. Will changing DNS settings affect my internet speed?

Usually, using OpenDNS can slightly improve DNS resolution times, potentially making browsing faster. However, if misconfigured, it might cause delays. Always verify your DNS settings.

6. What if I want to block websites on specific devices only?

In that case, you can configure DNS settings directly on the device or use device-specific parental controls. The router-based method affects all devices on the network.

Implementing website blocking with OpenDNS on your home WiFi provides a simple, effective way to control online content across all your devices. Regularly update your block list and verify your settings to maintain a safe and productive internet environment at home.
