Web Services
35%The domain has at least one IPv6 address (AAAA DNS record).
✓ 2606:4700::6812:7c6, 2606:4700::6812:6c6
The IPv6 addresses are publicly routable — not link-local, ULA, loopback or documentation ranges.
✓ All addresses are globally routable.
Website reachable on port 80 when connecting via IPv6.
✓ HTTP (port 80) responds over IPv6 — 40ms TTFB.
Website reachable on port 443 when connecting via IPv6.
✓ HTTPS (port 443) responds over IPv6 — 10ms TTFB.
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.
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 = WE1, expires May 29 20:30:23 2026 GMT
The domain has both A and AAAA records for backwards compatibility during the IPv6 transition.
✓ Domain has both A and AAAA records.
Server advertises HTTP/3 support via the Alt-Svc: h3 header.
✓ Alt-Svc: h3 header detected.
DNS & DNSSEC
25%At least one authoritative nameserver has an IPv6 address (AAAA record).
✓ Nameserver has IPv6 address.
Authoritative nameserver accepts TCP connections on port 53 over IPv6.
✓ Nameserver is reachable via IPv6 on port 53.
Nameserver actually resolves DNS queries when asked over IPv6 — not just TCP open, but functionally answering.
✓ DNS queries answered over IPv6.
Full DNSSEC chain-of-trust validation passes. Prevents DNS cache poisoning and spoofing.
✓ DNSSEC fully validated.
A PTR record exists in ip6.arpa for the IPv6 address. Important for email delivery and network diagnostics.
✗ No PTR record found.
Delegation Signer record exists in the parent zone.
✓ DS record found at parent zone.
RRSIG signatures are present and not expired.
✓ RRSIG signatures are current and valid.
The cryptographic algorithm used for DNSSEC signing.
ECDSAP256SHA256
Email Services
25%The domain has at least one MX (Mail Exchange) DNS record pointing to a mail server.
✓ MX record found.
The highest-priority MX server resolves to an IPv6 address (AAAA record).
✗ MX server has no IPv6 address.
The MX server accepts SMTP connections (port 25) over IPv6 and responds with a 220 banner.
✗ SMTP is not reachable over IPv6.
The MX server supports STARTTLS encryption when connected over IPv6.
✗ STARTTLS not available over IPv6.
A TXT record with v=spf1 exists, declaring which servers may send email for this domain.
✓ SPF record found.
A DKIM public key is published at a common selector, enabling email signature verification.
DKIM selector found: k1._domainkey
A DMARC policy record exists at _dmarc.<domain>, enabling email authentication reporting.
✓ DMARC record found.
IPv4 Baseline
15%The domain has at least one IPv4 address (A DNS record).
✓ 104.18.7.198, 104.18.6.198
Website reachable on port 80 when connecting via IPv4.
✓ HTTP (port 80) responds over IPv4 — 7ms TTFB.
Website reachable on port 443 when connecting via IPv4.
✓ HTTPS (port 443) responds over IPv4 — 14ms TTFB.
DNS Resolution Performance
Comparison of A (IPv4) vs AAAA (IPv6) query times across resolvers and transports. Shows median (p50) of 3 samples.
| Resolver | Transport | A (IPv4) | AAAA (IPv6) | Delta |
|---|---|---|---|---|
| System | Default | 6.94 ms (p95: 7.03) | 6.92 ms (p95: 7.01) | -0 ms |
| IPv4 | 20.9 ms (p95: 23.07) | 15.95 ms (p95: 28.28) | -5 ms | |
| IPv6 | 22.42 ms (p95: 28.66) | 19.93 ms (p95: 30.02) | -2.5 ms | |
| Cloudflare | IPv4 | 20.06 ms (p95: 26.02) | 19.94 ms (p95: 22.84) | -0.1 ms |
| Cloudflare | IPv6 | 21 ms (p95: 22.93) | 20.7 ms (p95: 28.09) | -0.3 ms |
