Web Services
35%The domain has at least one IPv6 address (AAAA DNS record).
✗ No AAAA record found in DNS.
The IPv6 addresses are publicly routable — not link-local, ULA, loopback or documentation ranges.
✗ IPv6 address is not 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 is IPv6-only or IPv4-only.
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: default._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).
✓ 103.228.54.223
Website reachable on port 80 when connecting via IPv4.
✓ HTTP (port 80) responds over IPv4 — 299ms TTFB.
Website reachable on port 443 when connecting via IPv4.
✓ HTTPS (port 443) responds over IPv4 — 255ms 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 | 11.69 ms (p95: 23.27) | 10.73 ms (p95: 22.64) | -1 ms |
| IPv4 | 41.36 ms (p95: 65.22) | 29.45 ms (p95: 66.71) | -11.9 ms | |
| IPv6 | 30.18 ms (p95: 70.15) | 18.93 ms (p95: 20.1) | -11.3 ms | |
| Cloudflare | IPv4 | 9.93 ms (p95: 19.13) | 10.63 ms (p95: 21.02) | +0.7 ms |
| Cloudflare | IPv6 | 37.1 ms (p95: 50.95) | 42.55 ms (p95: 53.58) | +5.5 ms |
