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: ns1.uwimona.edu.jm, ns2.uwimona.edu.jm.
Publish AAAA records for mail (MX): vision.uwimona.edu.jm.
Web measurement was inconclusive or unavailable.
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.

Checks

DNS

IPv4-only

[2] 0/0/0 [I]

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 I

Host	IPv4	IPv6	Probes
`ns1.uwimona.edu.jm` [I]	196.2.1.2	—	ipv4 196.2.1.2 ok;
`ns2.uwimona.edu.jm` [I]	196.2.1.3	—	ipv4 196.2.1.3 ok;

📌 Action item(s):

Publish AAAA records for name server: ns1.uwimona.edu.jm, ns2.uwimona.edu.jm.

Mail

IPv4-only

[1 MX] v4 smtp 1/1/1 v6 smtp 0/0/0 [I]

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

IPv4 SMTP 1/1/1 · IPv6 0/0/0 · location I

Host	IPv4	IPv6	Probes
`vision.uwimona.edu.jm` [I]	196.2.1.242	—	ipv4 196.2.1.242 ok;

📌 Action item(s):

Publish AAAA records for mail (MX): vision.uwimona.edu.jm.

Web

Unknown

[0] error: Get "https://www.uwimona.edu.jm/": tls: failed to verify certificate: x509: certificate is valid for cds.mona.uwi.edu, not www.uwimona.edu.jm

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

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.uwimona.edu.jm (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.

Record at _dmarc.uwimona.edu.jm:

v=DMARC1; p=none; rua=mailto:mailadmin@uwimona.edu.jm; ruf=mailto:mailadmin@uwimona.edu.jm; adkim=r; aspf=r; fo=1

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

📌 Action item(s):

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