DNS Testor: a leak test that won’t call a clue proof
A browser-based DNS test for comparing resolver observations before and after connecting to a VPN, with local baselines and JSON or CSV exports.
- For
- VPN users checking DNS behavior
- Worth noticing
- The page says multiple resolvers, AAAA queries, and missing samples cannot by themselves establish a leak or a pass.
Field notes
The page offers standard and expanded sampling, with fresh per-test domains intended to reduce cache effects. It separates authoritative-DNS resolver observations from HTTPS probe source addresses, supports a browser-local baseline and JSON/CSV exports, and warns that exported reports include network addresses. Its methodology says resolver observations reveal the resolver exit, not the device-to-resolver path; packet capture or client-side evidence may still be needed.
