Domain Name System | What is DNS in Depth

Every time you open a website, your Internet Provider logs it. And by law, they hand that data to the government. Most developers think switching to 1.1.1.1 fixes this. It does not. Your ISP can still see every domain you visit — even with a different DNS. In this video I broke down exactly how DNS privacy works from first principles. Not just what DoH and ECH are — but why they were built, what problem they solve, and where they still fail. You will understand why HTTPS alone is not enough. Why changing DNS is not enough. Why even DoH is not enough. And what the complete privacy stack actually looks like. This is not a tutorial. This is how the internet actually works — and why your browsing is more exposed than you think. What we covered: How your ISP sees your DNS queries Why changing to Cloudflare DNS is not enough What SNI is and why it leaks your domain name How DoH encrypts your DNS traffic How ECH hides your domain from ISP completely What TLS handshake actually does How certificates prove a server's identity The complete privacy stack — DoH + ECH + HTTPS Enroll in Our Premium Courses: DSA: https://strikes.in/course/combo Web Dev: https://coderarmy.in/#home AI: https://strikes.in/course/689ee05f1d8...
