Opera GX and DNS over HTTPS: A Comprehensive Guide

What is DNS over HTTPS (DoH)?

DNS over HTTPS (DoH) is a method of encrypting your Domain Name System (DNS) lookups. Normally, when you type a website address into your browser, your computer contacts a DNS server (like Google's 8.8.8.8 or Cloudflare's 1.1.1.1) to translate that address (e.g., www.example.com) into a numerical IP address that your computer can use to connect to the website. This communication happens in plain text, making your browsing activity potentially visible to your internet service provider (ISP) and anyone intercepting your network traffic.

DoH encrypts this communication using HTTPS, the same protocol that secures your web browsing. This means your DNS queries are hidden from prying eyes, protecting your privacy and potentially enhancing your security.

Why Use DoH with Opera GX?

Opera GX, a browser tailored for gamers, offers built-in support for DoH, adding another layer of privacy and security to your online experience. Using DoH with Opera GX offers several benefits:

• Increased Privacy: Your DNS queries are encrypted, preventing your ISP and other potential eavesdroppers from seeing which websites you're visiting.
• Enhanced Security: DoH protects you from DNS spoofing and other DNS-based attacks that could redirect you to malicious websites.
• Improved Performance (Potentially): Some DoH providers offer faster DNS resolution times, leading to quicker website loading.
• Censorship Circumvention (Potentially): In regions with internet censorship, DoH can help bypass restrictions on accessing certain websites.

Enabling DoH in Opera GX

Enabling DoH in Opera GX is straightforward. The exact steps might vary slightly depending on your Opera GX version, but the general process is as follows:

1. Open Opera GX and click on the Settings menu (usually represented by a gear icon).
2. Navigate to Privacy & security.

4. Select your preferred DoH provider. Opera GX usually offers a few options, including its own service and popular providers like Cloudflare and Google Public DNS.
5. Restart Opera GX for the changes to take effect.

If you can't find the DNS over HTTPS option, check for updates to ensure you have the latest version of Opera GX.

Choosing a DoH Provider

Opera GX typically gives you a few DoH provider choices. Each provider has its own privacy policies and performance characteristics. Consider the following when choosing:

• Privacy Policy: Review the privacy policy of each provider to understand how they handle your DNS data.
• Performance: Some providers may offer faster DNS resolution times than others.
• Security: Ensure the provider has a strong reputation for security.

Research different providers before making a decision. Reading reviews and comparing their features can help you choose the best option for your needs.

If you encounter issues after enabling DoH, try the following troubleshooting steps:

• Restart your computer: Sometimes, a simple restart can resolve connectivity problems.
• Check your network connection: Ensure your internet connection is stable and working correctly.
• Disable other VPNs or proxies: Conflicts with other network tools can interfere with DoH functionality.
• Try a different DoH provider: If one provider isn't working, try another.
