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

Priority next steps

DNS measurement was inconclusive or unavailable.
Enable DNSSEC signing and publish a DNSKEY at the apex. Use DNSViz to validate the full chain.

Unknown

[0] -/-/- [-]

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

IPv4 0/0/0 · IPv6 0/0/0 · location -

📌 Action item(s):

Dual-stack

[1 MX] v4 smtp 4/4/4 v6 smtp 4/4/4 [O]

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

Host	IPv4	IPv6	Probes
`ogp-pr-gov.mail.protection.outlook.com` [O]	52.101.60.170, 52.101.41.204, 52.101.60.145, 52.101.60.168	2a01:111:f403:c927::5, 2a01:111:f403:f90b::5, 2a01:111:f403:f801::1, 2a01:111:f403:c803::a	ipv4 52.101.60.170 ok; ipv4 52.101.41.204 ok; ipv4 52.101.60.145 ok; ipv4 52.101.60.168 ok; ipv6 2a01:111:f403:c927::5 ok; ipv6 2a01:111:f403:f90b::5 ok; ipv6 2a01:111:f403:f801::1 ok; ipv6 2a01:111:f403:c803::a ok;

Dual-stack

[1] 1/1/1 [I]

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

IPv4 1/1/1 · IPv6 1/1/1 · location I

Host	IPv4	IPv6	Probes
`www.ogp.pr.gov` [I]	198.202.211.1	2620:cb:2000::1	ipv4 ok; ipv6 ok;

Unsigned

U/-/-

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.

📌 Action item(s):

Enable DNSSEC signing and publish a DNSKEY at the apex. Use DNSViz to validate the full chain.

p=reject

p=reject — published organizational policy. Strongest published policy (SPF/DKIM alignment still not measured here).

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

Record at _dmarc.ogp.pr.gov:

v=DMARC1; p=reject; pct=100; rua=mailto:dmarc@ogp.pr.gov; ruf=mailto:dmarc@ogp.pr.gov

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