Web Services
35%The domain has at least one IPv6 address (AAAA DNS record).
✓ 2a06:98c1:3107::ac40:9173, 2a06:98c1:3109::6812:2a8d
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 — 87ms TTFB.
Website reachable on port 443 when connecting via IPv6.
✓ HTTPS (port 443) responds over IPv6 — 45ms TTFB.
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 = SSL Corporation, CN = Cloudflare TLS Issuing ECC CA 3, expires Nov 21 10:33:20 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.
✗ 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.
✓ 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 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).
✓ 13.249.231.127, 13.249.231.87, 13.249.231.74, 13.249.231.76
Website reachable on port 80 when connecting via IPv4.
✓ HTTP (port 80) responds over IPv4 — 71ms TTFB.
Website reachable on port 443 when connecting via IPv4.
✓ HTTPS (port 443) responds over IPv4 — 46ms 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 | 8.71 ms (p95: 9.39) | 22.71 ms (p95: 23.16) | +14 ms |
| IPv4 | 31.23 ms (p95: 41.36) | 30.36 ms (p95: 33.76) | -0.9 ms | |
| IPv6 | 35.2 ms (p95: 38.25) | 23.64 ms (p95: 29.32) | -11.6 ms | |
| Cloudflare | IPv4 | 25.68 ms (p95: 41.73) | 22.55 ms (p95: 27.02) | -3.1 ms |
| Cloudflare | IPv6 | 20.04 ms (p95: 41.39) | 19.47 ms (p95: 22.05) | -0.6 ms |
