btnp.org — Caribbean IPv6 Monitor

Score1/4

Overall IPv4-only

Collected2026-09-29 10:19 UTC

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

Priority next steps

Publish AAAA records / enable IPv6 on MX hosts.
Web measurement was inconclusive or unavailable.
Enable DNSSEC signing and publish a DNSKEY at the apex. Use DNSViz to validate the full chain.
Publish a _dmarc TXT record (start with p=none, then tighten). Check policy on dmarcian.

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

Checks

DNS

Dual-stack

[6] 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

IPv4-only

[2 MX] v4 smtp 2/2/2 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 2/2/2 · IPv6 0/0/0 · location O

📌 Action item(s):

Publish AAAA records / enable IPv6 on MX hosts.

Web

Unknown

[0] error: Get "https://www.btnp.org/": tls: failed to verify certificate: x509: certificate is valid for *.pressable.com, pressable.com, not www.btnp.org

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

IPv4 0/0/0 · IPv6 0/0/0 · location -

📌 Action item(s):

Web measurement was inconclusive or unavailable.

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

No record

No record — no TXT at _dmarc.btnp.org.

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

Publish a DMARC TXT at _dmarc.btnp.org (often start with p=none, then tighten).

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

Check on dmarcian

📌 Action item(s):

Publish a _dmarc TXT record (start with p=none, then tighten). Check policy on dmarcian.
