Work only inside the folder created by Smartphone-Academy.py prepare dns-resolver-comparison. Use the supplied samples, your own phone, or systems you are explicitly authorized to administer.
Prepare the Termux workspace
Open Termux in the Academy root and prepare this lab with the local companion. It creates safe samples, notes and evidence files under your Termux account.
python Smartphone-Academy.py prepare dns-resolver-comparisonNo root. Keep the workspace under $HOME and avoid personal identifiers in evidence.Practical mission
- Identify the resolver currently used by the phone and Termux
- Query the same harmless domains through multiple documented resolvers
- Compare timing, filtering, DNSSEC indicators and answer consistency
- Explain what the test can and cannot prove about privacy
A resolver comparison table with commands, timings, answer differences and limitations.

Analyst reflection
Which result from “Explain what the test can and cannot prove about privacy” needs stronger evidence before it can support a real decision?
After checking the evidence, run python Smartphone-Academy.py complete dns-resolver-comparison. Progress is stored locally in the Termux home directory.
