DNS over HTTPS (DoH) in Vivaldi: A Comprehensive Guide

Vivaldi, known for its customization options and privacy features, offers robust support for DNS over HTTPS (DoH). This guide will walk you through understanding DoH, its benefits, how to configure it in Vivaldi, troubleshooting common issues, and exploring alternative methods.

What is DNS over HTTPS (DoH)?

DNS, or Domain Name System, translates human-readable domain names (like google.com) into machine-readable IP addresses. Traditionally, this communication happens over UDP or TCP, which are susceptible to eavesdropping and manipulation. DoH encrypts this DNS traffic over HTTPS, the same protocol used for secure web browsing. This encryption prevents your ISP or other third parties from seeing which websites you're visiting.

Benefits of using DoH in Vivaldi

• Enhanced Privacy: Masks your browsing activity from your ISP and potential network eavesdroppers.
• Improved Security: Protects against DNS spoofing and other DNS-based attacks.
• Faster Resolving: Some DoH providers offer faster DNS resolution times than traditional DNS servers.
• Censorship Resistance: Can bypass certain forms of DNS censorship.

Configuring DoH in Vivaldi

Vivaldi offers a straightforward way to configure DoH. Follow these steps:

1. Open Vivaldi's settings (Menu > Settings or press F12).
2. Navigate to the "Privacy" section.
3. Find the "DNS over HTTPS" option (it may be under a sub-section like "Network").
4. Enable the "Use DNS over HTTPS" toggle.
5. Select a DoH provider from the dropdown menu. Vivaldi usually provides a few reputable options, such as Cloudflare (https://cloudflare-dns.com/dns-query) or Google Public DNS (https://dns.google/dns-query).
6. You can also manually specify a custom DoH server address. Make sure to enter the correct URL. (e.g., https://your-doh-provider.com/dns-query)
7. Restart Vivaldi for the changes to take effect.

Choosing a DoH Provider

The choice of DoH provider depends on your priorities. Some providers might prioritize speed, while others might focus on privacy. Research different providers and their privacy policies before making a decision. Consider factors like location, logging policies, and any potential censorship.

Troubleshooting DoH in Vivaldi

If you encounter problems after enabling DoH, try the following:

• Verify the DoH server address: Ensure you've entered the correct address and it's accessible.
• Restart Vivaldi: A simple restart often resolves minor issues.
• Check your network settings: Make sure there are no firewall or proxy settings blocking DoH traffic.
• Try a different DoH provider: If one provider isn't working, try another.
• Disable other extensions or VPNs: Conflicts with other extensions or VPNs can sometimes disrupt DoH functionality.

Alternative Methods for Enhanced DNS Privacy

Besides DoH, other methods enhance your DNS privacy. However, DoH is often the easiest and most integrated solution:

• Using a VPN: A VPN encrypts all your internet traffic, including DNS queries, offering comprehensive privacy protection, but can impact speed and costs money.
• Configuring DNS on your Router: Some routers allow you to configure DoH directly at the router level, protecting all devices connected to your network.

By enabling DoH in Vivaldi, you can significantly enhance your online privacy and security. Remember to choose a reputable DoH provider and stay informed about potential issues and alternative methods to safeguard your digital footprint.
