Web Services
35%The domain has at least one IPv6 address (AAAA DNS record).
✓ 2401:74a0:140::16
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 is not accessible over IPv6.
Website reachable on port 443 when connecting via IPv6.
✗ HTTPS is not accessible over IPv6.
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.
✗ TLS certificate is invalid, expired, or hostname mismatch over IPv6.
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.
✗ No HTTP/3 support 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.
✗ No nameserver is reachable over IPv6.
Nameserver actually resolves DNS queries when asked over IPv6 — not just TCP open, but functionally answering.
✗ Nameserver does not answer queries 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 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.
No common DKIM selector found.
A DMARC policy record exists at _dmarc.<domain>, enabling email authentication reporting.
✗ No DMARC record found.
IPv4 Baseline
15%The domain has at least one IPv4 address (A DNS record).
✓ 202.58.83.54
Website reachable on port 80 when connecting via IPv4.
✓ HTTP (port 80) responds over IPv4 — 184ms TTFB.
Website reachable on port 443 when connecting via IPv4.
✓ HTTPS (port 443) responds over IPv4 — 167ms 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 | 20.32 ms (p95: 20.82) | 11.83 ms (p95: 24.13) | -8.5 ms |
| IPv4 | 29.15 ms (p95: 29.56) | 29.97 ms (p95: 30.64) | +0.8 ms | |
| IPv6 | 27.36 ms (p95: 41.06) | 20.59 ms (p95: 28.59) | -6.8 ms | |
| Cloudflare | IPv4 | 10.34 ms (p95: 22.01) | 9.01 ms (p95: 9.08) | -1.3 ms |
| Cloudflare | IPv6 | 19.1 ms (p95: 19.54) | 28.14 ms (p95: 40.62) | +9 ms |
