Measurement estimates from a single vantage point — not a compliance certification. Guidance below is for operators, not an SLA.
DNS
Dual-stack
[7] 3/2/2 [O]
Meaning: Shows how many authoritative name servers exist, and how many IPv6 endpoints are configured, responsive, and operational.

📌 Action item(s):
- Publish AAAA records for name server: ns1.web.infochange.com, ns3.web.infochange.com, ns4.web.infochange.com, ns5.web.infochange.com.
- IPv6 2a01:7e00::f03c:91ff:fe93:b194 on name server ns7.web.infochange.com failed (refused) — check firewall, routing, and service.
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.

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 |

63.142.241.237 |
— |
ipv4 ok; |
📌 Action item(s):
- Publish AAAA records for web host: our.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=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.our.org.jm (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.
Record at _dmarc.our.org.jm:
v=DMARC1; pct=100; ruf=mailto:postmaster@our.org.jm; rua=mailto:postmaster@our.org.jm; p=none
Policy publication only — SPF/DKIM not measured. Not part of the 0–4 row score.
Check on dmarcian
📌 Action item(s):
- DMARC is monitoring-only (p=none). Move toward quarantine, then reject. Review on dmarcian.
