How to read these results

Fresh random hostnames reveal recursive DNS addresses through independent services. Registered country may differ from node location. DNS resolver and web IP addresses normally differ.

Failures may be caused by timeout, cross-origin restrictions, browser extensions or upstream limits. Missing results are not treated as healthy or unlocked. Retry failed items, or compare local history after switching networks.
