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

Priority next steps

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.

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

Checks

DNS

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

Mail

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.

IPv4 SMTP 4/4/4 · IPv6 4/4/4 · location O

Web

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.

IPv4 2/2/2 · IPv6 2/2/2 · location I

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

none

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.visitbarbados.org (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.

DMARC is monitoring-only (p=none). Move toward quarantine, then reject. Review on dmarcian.
