IPv4 Addresses Detected
103.86.179.184
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).
✗ No nameserver has an AAAA record.
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.
✓ 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: selector1._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).
✓ 103.86.179.184
Website reachable on port 80 when connecting via IPv4.
✓ HTTP (port 80) responds over IPv4 — 669ms TTFB.
Website reachable on port 443 when connecting via IPv4.
✓ HTTPS (port 443) responds over IPv4 — 19ms 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 28% 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 | 22.28 ms (p95: 22.94) | 21.46 ms (p95: 22.11) | -0.8 ms |
| IPv4 | 42.82 ms (p95: 147.13) | 153.98 ms (p95: 159.03) | +111.2 ms | |
| IPv6 | 148.97 ms (p95: 149.08) | 402.23 ms (p95: 469.53) | +253.3 ms | |
| Cloudflare | IPv4 | 35.72 ms (p95: 37.11) | 64.51 ms (p95: 101.79) | +28.8 ms |
| Cloudflare | IPv6 | 60.76 ms (p95: 91.07) | 32.08 ms (p95: 49.52) | -28.7 ms |
