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 for name server: ns.cwjamaica.com, ns1.cwjamaica.com.
Publish AAAA records for mail (MX): mail.boj.org.jm, mail2.boj.org.jm, mail3.boj.org.jm, mx01.cwjamaica.com, mx02.cwjamaica.com.
Publish AAAA records for web host: boj.org.jm.
Enable DNSSEC signing and publish a DNSKEY at the apex. Use DNSViz to validate the full chain.
Tighten DMARC toward p=reject when ready. Review on dmarcian.

Checks

DNS

IPv4-only

[2] 0/0/0 [O]

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

IPv4 2/2/2 · IPv6 0/0/0 · location O

Host	IPv4	IPv6	Probes
`ns1.cwjamaica.com` [O]	200.10.152.152	—	ipv4 200.10.152.152 ok;
`ns.cwjamaica.com` [O]	200.10.152.232	—	ipv4 200.10.152.232 ok;

📌 Action item(s):

Publish AAAA records for name server: ns.cwjamaica.com, ns1.cwjamaica.com.

Mail

IPv4-only

[5 MX] v4 smtp 5/5/4 v6 smtp 0/0/0 [M]

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

IPv4 SMTP 5/5/4 · IPv6 0/0/0 · location M

Host	IPv4	IPv6	Probes
`mail3.boj.org.jm` [I]	63.143.111.232	—	ipv4 63.143.111.232 ok;
`mail2.boj.org.jm` [I]	208.131.174.77	—	ipv4 208.131.174.77 timeout;
`mx01.cwjamaica.com` [O]	200.10.152.53	—	ipv4 200.10.152.53 ok;
`mx02.cwjamaica.com` [O]	200.10.152.54	—	ipv4 200.10.152.54 ok;
`mail.boj.org.jm` [I]	208.138.36.167	—	ipv4 208.138.36.167 ok;

📌 Action item(s):

Publish AAAA records for mail (MX): mail.boj.org.jm, mail2.boj.org.jm, mail3.boj.org.jm, mx01.cwjamaica.com, mx02.cwjamaica.com.

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
`boj.org.jm` [I]	181.224.131.33	—	ipv4 ok;

📌 Action item(s):

Publish AAAA records for web host: boj.org.jm.

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=quarantine

p=quarantine — published organizational policy. Ask receivers to quarantine failing mail; reject is stronger.

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

Record at _dmarc.boj.org.jm:

v=DMARC1; p=quarantine; fo=1; rua=mailto:dmarc_rua@emaildefense.proofpoint.com; ruf=mailto:dmarc_ruf@emaildefense.proofpoint.com

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

📌 Action item(s):

Tighten DMARC toward p=reject when ready. Review on dmarcian.
