Measurement estimates from a single vantage point — not a compliance certification. Guidance below is for operators, not an SLA.

Priority next steps

Host-level detail (NS/MX/web addresses and probe outcomes) appears after the next collector run (v0.4+).

Dual-stack

[2] 6/6/6 [O]

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

IPv4 6/6/6 · IPv6 6/6/6 · location O

Dual-stack

[7 MX] v4 smtp 7/7/7 v6 smtp 7/7/7 [O]

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

IPv4 SMTP 7/7/7 · IPv6 7/7/7 · location O

IPv4-only

[1] 0/0/0 [I]

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

IPv4 3/3/3 · IPv6 0/0/0 · location I

📌 Action item(s):

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, sp=none

p=quarantine, sp=none — published organizational policy. Ask receivers to quarantine failing mail; reject is stronger.

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

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