Dual-Stack Diagnostic

Explain why IPv4 and IPv6 do not behave the same.

This page calls the existing /v1/assessment API and derives the differences in the browser. It does not change the public API contract.

Use the local consistency checks as a self-check when a VPN or proxy may route IPv4 and IPv6 differently.

The current IP inputs are compared against this browser's timezone and language settings. The defaults are examples, not automatically detected visitor addresses; replace them with your own IPv4 and IPv6 exit IPs, then choose Diagnose for a personal VPN or proxy self-check.
