HTTPS over IPv6

Website reachable on port 443 when connecting via IPv6.

✗ HTTPS is not accessible over IPv6.

0
IPv6-Only Reachability

Website responds when connected exclusively over IPv6, with no IPv4 fallback. Simulates what happens when IPv4 is turned off.

✗ Site is not reachable when limited to IPv6-only.

0
TLS Certificate Valid (IPv6)

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

✗ TLS certificate is invalid, expired, or hostname mismatch over IPv6.

0
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.
