Measurement estimates from a single vantage point — not a compliance certification. Guidance below is for operators, not an SLA.
DNS
IPv4-only
[3] 0/0/0 [O]
Meaning: Shows how many authoritative name servers exist, and how many IPv6 endpoints are configured, responsive, and operational.
IPv4 3/3/3 · IPv6 0/0/0 · location O
| Host | IPv4 | IPv6 | Probes |
|---|
dns.fsl.org.jm [O] |
196.3.191.6 |

ipv4 196.3.191.6 ok; |

ipv4 196.3.188.11 ok; |
dns2.fsl.org.jm [O] |
196.3.191.26 |
— |
ipv4 196.3.191.26 ok; |
📌 Action item(s):
- Publish AAAA records for name server: dns.fsl.org.jm, dns2.fsl.org.jm, dns3.fsl.org.jm.
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
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 |
|---|
www.mset.gov.jm [I] |
196.3.190.41 |
— |
ipv4 ok; |
📌 Action item(s):
- Publish AAAA records for web host: www.mset.gov.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.mset.gov.jm (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.
Record at _dmarc.mset.gov.jm:
v=DMARC1; p=quarantine; rua=mailto:DMARC@mset.gov.jm; ruf=mailto:DMARC@mset.gov.jm
Policy publication only — SPF/DKIM not measured. Not part of the 0–4 row score.
Check on dmarcian
📌 Action item(s):
- Tighten DMARC toward p=reject when ready. Review on dmarcian.
