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

Priority next steps

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

Dual-stack

[2] 2/2/2 [O]

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

IPv4 2/2/2 · IPv6 2/2/2 · location O

Host	IPv4	IPv6	Probes
`ns2.dns-parking.com` [O]	162.159.25.42	2400:cb00:2049:1::a29f:192a	ipv4 162.159.25.42 ok; ipv6 2400:cb00:2049:1::a29f:192a ok;
`ns1.dns-parking.com` [O]	162.159.24.201	2400:cb00:2049:1::a29f:18c9	ipv4 162.159.24.201 ok; ipv6 2400:cb00:2049:1::a29f:18c9 ok;

Mail

Dual-stack

[2 MX] v4 smtp 2/2/2 v6 smtp 2/2/2 [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 2/2/2 · location O

Host	IPv4	IPv6	Probes
`mx2.hostinger.com` [O]	172.65.182.103	2606:4700:90:0:c1f8:f874:2386:b61f	ipv4 172.65.182.103 ok; ipv6 2606:4700:90:0:c1f8:f874:2386:b61f ok;
`mx1.hostinger.com` [O]	172.65.182.103	2606:4700:90:0:c1f8:f874:2386:b61f	ipv4 172.65.182.103 ok; ipv6 2606:4700:90:0:c1f8:f874:2386:b61f ok;

Web

Dual-stack

[1] 2/2/2 [I]

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

IPv4 2/2/2 · IPv6 2/2/2 · location I

Host	IPv4	IPv6	Probes
`education.gov.bb` [I]	92.113.23.34, 92.113.16.236	2a02:4780:45:696f:4b10:3881:9bc9:2513, 2a02:4780:43:31df:d93f:618a:5e0d:b12c	ipv4 ok; ipv6 ok;

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.education.gov.bb (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.

Record at _dmarc.education.gov.bb:

v=DMARC1; p=none

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.
