Your Fancy DNS Tricks Won’t Give You Privacy

Encrypted DNS, Pi-hole, Unbound, Cloudflare, and Quad9 can hide or reduce DNS exposure, but that does not automatically stop your ISP from seeing which websites you visit. In this hands-on test, David uses a Raspberry Pi, Python scripts, and a network tap to show how an ISP-like observer can still log website destinations through TLS/SNI traffic, even when DNS queries are hidden. We test multiple setups, including DNS over HTTPS, Pi-hole, Unbound, Cloudflare, and browser secure DNS settings, then compare what disappears from DNS logs versus what still shows up in live connection metadata. If you think encrypted DNS alone gives you browsing privacy, this demonstration may change how you think about ISP tracking, website blocking, and the limits of DNS privacy. // Python scripts // You can get the python scripts from GitHub here: DNS Monitor: https://github.com/davidbombal/sni-dn...
