How to Read Results

Each test cell combines a color status and a compact technical summary. The notes below explain both in plain language.

Status and points

IPv4-only No IPv6 operational path observed for this test result. (0 points per column)
Dual-stack Both IPv4 and IPv6 paths are present; IPv6 is available with IPv4. (1 point per column)
IPv6-only IPv6 path is operational for this test result. (1 point per column)
Unknown Measurement was not conclusive or the test was not available. (0 points per column)

Per-test output format

DNS

Format: [NS count] v6 configured/reachable/operational [location]

Meaning: Shows how many authoritative name servers exist, and how many IPv6 endpoints are configured, responsive, and operational.

Configured/Reachable/Operational maps to DNS server endpoints discovered from NS records.
Location tags indicate hosting locality context for the tested domain.

Mail

Format: [MX count] v4 smtp configured/reachable/operational v6 smtp configured/reachable/operational [location]

Meaning: Shows MX footprint and SMTP health per IP family. Operational means an SMTP banner and EHLO exchange succeeded on port 25.

v4 and v6 SMTP are measured separately.
MX presence without successful SMTP handshake can still produce non-operational results.

Web

Format: [site count] v6 configured/reachable/operational [location]

Meaning: Shows IPv6 web endpoint readiness for the discovered HTTPS host. Operational means family-specific HTTPS requests complete successfully.

Configured/Reachable are derived from discovered A/AAAA records on the final web host.
Operational reflects request success by family (tcp4 and tcp6 tested separately).

DNSSEC

Format: S/?/? (partial), U/-/-, or error text

Meaning: Shows whether DNSKEY data is observed at the apex (signed), absent (unsigned), or unavailable due to lookup error.

S/?/? (partial) indicates partial DNSSEC signal only.
Full chain validation is not yet performed by this checker.

Location tag key

[I] Inside: Service hostname is the tested domain or a subdomain under it.
[P] Parent-related: Service hostname resolves via a parent/suffix relationship to the tested domain.
[O] Outside: Service hostname is outside the tested domain suffix.
[M] Mixed: Multiple service hosts span more than one location class.
[-] Not available: No location could be derived from the observed data.

How score is built

Row score: 0-4 points. Row score = DNS + Mail + Web + DNSSEC, where each column contributes 0 or 1 point.

IPv4-only: 0 points
Dual-stack: 1 point
IPv6-only: 1 point
Unknown: 0 points

DNSSEC uses signed=1 point; unsigned, error, and unknown=0 points.

Economy score: Economy deployment score (%) = average(RowScore/4) across domains x 100.
