Dual-stack

[1] 2/2/2 [I]

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

Signed

S/?/? (partial)

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

Apex DNSKEY presence only — not full chain validation.

p=quarantine

p=quarantine — published organizational policy. Ask receivers to quarantine failing mail; reject is stronger.

Meaning: Published DMARC policy at _dmarc.onecomm.bm (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.

Record at _dmarc.onecomm.bm:

v=DMARC1; p=quarantine; pct=100; rua=mailto:dmarc@onecomm.bm

Policy publication only — SPF/DKIM not measured. Not part of the 0–4 row score.
