The IPv6 addresses are publicly routable — not link-local, ULA, loopback or documentation ranges.

✓ All addresses are globally routable.

+1
HTTP over IPv6

Website reachable on port 80 when connecting via IPv6.

✓ HTTP (port 80) responds over IPv6 — 614ms TTFB.

+1
HTTPS over IPv6

✓ Site is fully reachable via IPv6-only.

+1
TLS Certificate Valid (IPv6)

The SSL/TLS certificate is valid, not expired, and matches the domain when connected via IPv6.

✓ Certificate valid — issued by C = US, O = Google Trust Services, CN = WR2, expires Apr 27 08:36:37 2026 GMT

+1
Dual-Stack (IPv4 + IPv6)

The domain has both A and AAAA records for backwards compatibility during the IPv6 transition.

✓ Domain has both A and AAAA records.
