DNS guides
DNS turns names like example.com into addresses. Whoever answers those lookups can steer where you end up, so it’s worth knowing who that is.

Why DNS matters on public WiFi
- Hotels and airports often answer lookups themselves to show a sign-in page.
- A tampered network can answer with wrong addresses; certificate warnings are your last line of defence.
- Encrypted DNS (Android Private DNS, DNS profiles, VPNs) hides lookups from the network.
