What does this test do?

Connection Protocol — Detects whether you reached this page over IPv4 or IPv6.

IPv4 Connectivity — Your browser tries to connect to an IPv4-only server (v4.ident.me).

IPv6 Connectivity — Your browser tries to connect to an IPv6-only server (v6.ident.me). If this succeeds, your network supports IPv6.

Dual-Stack Preference — Your browser connects to a dual-stack server (ident.me) that supports both protocols. The IP version it uses reveals your network's preference.
