eero and DNS over HTTPS (DoH): A Comprehensive Guide

DNS over HTTPS (DoH) is a privacy-enhancing technology that encrypts your DNS queries, preventing your internet service provider (ISP) and other potential eavesdroppers from seeing which websites you visit. eero, a popular mesh Wi-Fi system, offers varying levels of support for DoH, depending on your eero model and firmware version. This guide will delve into the details of using DoH with your eero network, addressing common questions and troubleshooting issues.

Understanding DNS over HTTPS

Traditionally, DNS queries are sent over unencrypted UDP or TCP, making them vulnerable to interception and manipulation. DoH solves this by encrypting these queries using HTTPS, the same protocol used for secure web browsing. This added layer of security protects your privacy and can improve the speed and reliability of your DNS resolution in some cases.

eero's Support for DNS over HTTPS

eero's approach to DoH is multifaceted. It doesn't have a built-in, universally enabled DoH option like some routers. Instead, its support depends primarily on the DNS provider you choose. If your chosen DNS provider supports DoH, eero will often automatically utilize it. However, the experience can vary. Some older eero models might require specific configurations or may not fully support DoH despite the DNS provider's capabilities.

Supported DNS Providers with DoH

• Cloudflare (1.1.1.1): Generally well-supported by eero. Often automatically uses DoH when configured.
• Google Public DNS (8.8.8.8): Generally well-supported. Similar to Cloudflare, it often automatically leverages DoH.
• Quad9 (9.9.9.9): Usually works with DoH, but may require manual configuration in some cases.
• Other Providers: Many other DNS providers support DoH. Check your provider's documentation to see if they're compatible with eero.

Configuring DoH on eero

The process of configuring DoH on eero primarily involves setting your custom DNS servers. This is typically done through the eero app:

1. Open the eero app on your smartphone or tablet.
2. Navigate to the settings menu (usually a gear icon).
3. Look for the 'Network' or 'DNS' settings.
4. Change the 'DNS Server' setting. Enter the addresses for your chosen DNS provider supporting DoH (e.g., 1.1.1.1 and 1.0.0.1 for Cloudflare).
5. Save the changes. Your eero system should now attempt to use DoH if the provider and eero's firmware support it.

Important Note: The exact steps might slightly vary depending on your eero app version and firmware. Consult the official eero support documentation for the most up-to-date instructions.

Troubleshooting DoH with eero

If you're having trouble getting DoH to work with your eero, here are some things to try:

• Check your eero firmware: Make sure your eero units are running the latest firmware. Updates often include improvements to DoH support.
• Verify DNS provider support: Confirm that your chosen DNS provider actively supports DoH.
• Restart your eero network: A simple reboot can sometimes resolve connectivity issues.
• Check for network conflicts: Ensure no other network configurations are interfering with DoH.
• Contact eero support: If the issue persists, reach out to eero's customer support for assistance.

Security and Privacy Considerations

While DoH enhances privacy, it's crucial to remember that it doesn't completely eliminate all privacy risks. Your DNS provider still has visibility into your DNS queries. Choose a reputable provider with a strong privacy policy.

Conclusion

Implementing DoH with eero can significantly improve your online privacy. While the setup isn't always straightforward and depends on various factors, the benefits often outweigh the potential challenges. By following the steps outlined above and consulting relevant documentation, you can successfully enable and utilize DoH for a more secure and private internet experience.
