Web Services
35%The domain has at least one IPv6 address (AAAA DNS record).
✓ 2606:4700::6812:14e9, 2606:4700::6812:15e9
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.
Website reachable on port 443 when connecting via IPv6.
✓ HTTPS (port 443) responds over IPv6.
Website responds when connected exclusively over IPv6, with no IPv4 fallback. Simulates what happens when IPv4 is turned off.
✓ Site is fully reachable via 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 Nov 2 06:34:43 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 validation failed or zone is unsigned.
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.
✗ No DS record at parent.
RRSIG signatures are present and not expired.
✗ No valid RRSIG found.
The cryptographic algorithm used for DNSSEC signing.
No DNSKEY record found.
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 AAAA record.
The MX server accepts SMTP connections (port 25) over IPv6 and responds with a 220 banner.
✓ SMTP port 25 responds over IPv6.
The MX server supports STARTTLS encryption when connected over IPv6.
✓ STARTTLS supported over IPv6.
A TXT record with v=spf1 exists, declaring which servers may send email for this domain.
✗ No SPF record found.
A DKIM public key is published at a common selector, enabling email signature verification.
DKIM selector found: google._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).
✓ 35.241.14.17
Website reachable on port 80 when connecting via IPv4.
✓ HTTP (port 80) responds over IPv4 — 135ms TTFB.
Website reachable on port 443 when connecting via IPv4.
✓ HTTPS (port 443) responds over IPv4 — 75ms TTFB.
Render-Path Dependencies
not weightedAn AAAA record on this domain says nothing about the stylesheets, scripts and fonts the page then loads from somewhere else. Those are scored here, separately, because a blended figure would flatter both numbers. This score does not affect the 86% above.
The dependency chain could not be walked because this check predates dependency scoring. This is recorded as unmeasured rather than counted against the domain.
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 | 22.76 ms (p95: 22.92) | 24.63 ms (p95: 27.56) | +1.9 ms |
| IPv4 | 91.48 ms (p95: 92.82) | 30.89 ms (p95: 84.05) | -60.6 ms | |
| IPv6 | 33.78 ms (p95: 81.22) | 88.16 ms (p95: 106.78) | +54.4 ms | |
| Cloudflare | IPv4 | 49.4 ms (p95: 66.72) | 31.04 ms (p95: 35.5) | -18.4 ms |
| Cloudflare | IPv6 | 31.25 ms (p95: 39.43) | 41.19 ms (p95: 47.04) | +9.9 ms |
