Yandex Browser and DNS over HTTPS (DoH): A Comprehensive Guide

DNS over HTTPS (DoH) is a method of encrypting Domain Name System (DNS) queries and responses, improving privacy and security. This guide will delve into how DoH works within Yandex Browser, its benefits, potential drawbacks, and how to configure it.

What is DNS over HTTPS (DoH)?

Traditionally, DNS queries are sent in plain text, making them vulnerable to eavesdropping and manipulation. DoH encrypts these queries and sends them over HTTPS, the same protocol used for secure web browsing. This means your ISP or any intermediary network node cannot see which websites you are trying to access.

The key benefit is enhanced privacy. Your DNS queries are protected from prying eyes, preventing potential tracking of your browsing activity. It also enhances security by protecting against DNS spoofing and other attacks that can redirect you to malicious websites.

DoH in Yandex Browser: How it Works

Yandex Browser, like many modern browsers, supports DoH. However, the implementation might differ slightly depending on your browser version and operating system. By default, Yandex Browser might use a built-in DoH provider or allow you to specify a custom one. This means that your DNS requests are handled securely without requiring additional extensions or configuration (in many cases).

Configuring DoH in Yandex Browser

While Yandex Browser often handles DoH automatically, you might want to customize the DoH provider or even disable it. Unfortunately, there isn't a direct, universal setting in the Yandex Browser interface to specifically enable or disable DoH. The settings are usually managed via the underlying system's network configuration or through advanced browser settings (which may vary depending on version).

Checking your current DNS settings (this is not a guaranteed method to confirm DoH usage, but can give hints):

• Open Yandex Browser settings.
• Look for network settings or proxy settings.
• Inspect if there is any mention of DNS addresses or servers. If you see addresses using the HTTPS protocol (e.g., something like `https://dns.google`), this suggests the browser might be using DoH.

To explicitly use a specific DoH provider, you may need to modify your system's DNS settings directly (outside of the Yandex Browser settings). This process differs significantly based on your operating system (Windows, macOS, Linux):

• Windows: You'd typically modify your network adapter settings to specify a custom DNS server address (using the HTTPS address of your chosen DoH provider).
• macOS: System Preferences → Network → Advanced → DNS. Add your preferred DoH server address here.
• Linux: The method varies depending on your distribution and desktop environment. You might edit your `/etc/resolv.conf` file or use your system's network manager to specify a DNS server. This should be done carefully and with caution, as incorrect modifications can disrupt your internet connectivity.

Popular DoH Providers

Several reputable organizations offer public DoH resolvers. These include:

• Google Public DNS over HTTPS: https://dns.google
• Cloudflare DNS over HTTPS: https://cloudflare-dns.com/dns-query
• Quad9 DNS over HTTPS: https://dns.quad9.net/dns-query

Benefits of Using DoH with Yandex Browser

• Increased Privacy: Protects your DNS queries from snooping by your ISP or other network entities.
• Enhanced Security: Mitigates risks from DNS spoofing and other attacks.
• Improved Performance: In some cases, DoH can lead to faster DNS resolution times.

Potential Drawbacks

• Reliance on Third-Party Providers: You are trusting the chosen DoH provider with your DNS queries. Select a trustworthy provider.
• Potential for Censorship: Some DoH providers might block or filter certain domains based on their policies.
• Compatibility Issues: While widely supported, some older networks or devices might not support DoH fully.

Conclusion

Using DoH with Yandex Browser enhances your online privacy and security. While Yandex Browser itself might not explicitly offer DoH configuration within its interface, you can leverage your operating system's network settings to use a preferred DoH provider. Weigh the benefits and drawbacks carefully before implementing it, selecting a reputable DoH provider you trust.
