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: dns1639.dizinc.com, dns1640.dizinc.com.
Publish AAAA records for mail (MX): mail.dominica.gov.dm.
Publish AAAA records for web host: dominica.gov.dm.
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
`dns1639.dizinc.com` [O]	107.190.139.59	—	ipv4 107.190.139.59 ok;
`dns1640.dizinc.com` [O]	107.190.139.60	—	ipv4 107.190.139.60 ok;

📌 Action item(s):

Publish AAAA records for name server: dns1639.dizinc.com, dns1640.dizinc.com.

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
`mail.dominica.gov.dm` [I]	199.127.198.52	—	ipv4 199.127.198.52 ok;

📌 Action item(s):

Publish AAAA records for mail (MX): mail.dominica.gov.dm.

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
`dominica.gov.dm` [I]	107.190.139.58	—	ipv4 ok;

📌 Action item(s):

Publish AAAA records for web host: dominica.gov.dm.

DNSSEC

Signed

S/?/? (partial)

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

DMARC

p=quarantine, sp=none

p=quarantine, sp=none — published organizational policy. Ask receivers to quarantine failing mail; reject is stronger.

Meaning: Published DMARC policy at _dmarc.dominica.gov.dm (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.

Record at _dmarc.dominica.gov.dm:

v=DMARC1; p=quarantine; sp=none; fo=1; ri=3600; rua=mailto:dominicagovdm@rua.agari.com,mailto:postmaster@dominica.gov.dm; ruf=mailto:dominicagovdm@ruf.agari.com,mailto:postmaster@dominica.gov.dm
