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.
Publish AAAA records for mail (MX): mail.gov.vc.
Publish AAAA records for web host: customs.gov.vc.
Enable DNSSEC signing and publish a DNSKEY at the apex. Use DNSViz to validate the full chain.
DMARC is monitoring-only (p=none). Move toward quarantine, then reject. Review on dmarcian.

Checks

DNS

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):

DNS measurement was inconclusive or unavailable.

Mail

IPv4-only

[1 MX] v4 smtp 1/1/1 v6 smtp 0/0/0 [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 1/1/1 · IPv6 0/0/0 · location O

Host	IPv4	IPv6	Probes
`mail.gov.vc` [O]	23.170.80.11	—	ipv4 23.170.80.11 ok;

📌 Action item(s):

Publish AAAA records for mail (MX): mail.gov.vc.

Web

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 1/1/1 · IPv6 0/0/0 · location I

Host	IPv4	IPv6	Probes
`customs.gov.vc` [I]	23.170.80.30	—	ipv4 ok;

📌 Action item(s):

Publish AAAA records for web host: customs.gov.vc.

DNSSEC

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.

Analyze on DNSViz

📌 Action item(s):

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

DMARC

p=none

p=none — published organizational policy. Monitoring only (receivers should not reject mail); tighten toward quarantine, then reject when ready. Not the same as missing DMARC.

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

Record at _dmarc.customs.gov.vc:

v=DMARC1; p=none; rua=mailto:admin@gov.vc

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