DNS-over-HTTPS (DoH)
A secure way to look up website addresses that hides your internet traffic from hackers.
Detailed Explanation
DNS-over-HTTPS (DoH) is a security protocol that encrypts standard plaintext DNS queries over the Hypertext Transfer Protocol Secure (HTTPS). The goal of DoH is to increase user privacy and security by preventing eavesdropping and manipulation of DNS data by man-in-the-middle attacks, ISPs, and malicious network operators. You can test this using the DNS Lookup tool.
Key Technical Takeaways
- Encrypts DNS requests using standard TLS port 443.
- Prevents ISP snooping, DNS poisoning, and public Wi-Fi eavesdropping.
- Supported by major public DNS resolvers including Cloudflare (1.1.1.1) and Google (8.8.8.8).
- Allows browser-based client applications to query DNS records directly without custom backend proxies.
