Score1/4

Overall IPv4-only

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 mail (MX): mail.gov.vc.
Publish AAAA records for web host: www.gov.vc.
Enable DNSSEC signing and publish a DNSKEY at the apex. Use DNSViz to validate the full chain.

Dual-stack

[4] 4/4/4 [O]

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

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.gov.vc` [I]	23.170.80.11	—	ipv4 23.170.80.11 ok;

📌 Action item(s):

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.gov.vc` [I]	23.170.80.10	—	ipv4 ok;

📌 Action item(s):

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.

📌 Action item(s):

Enable DNSSEC signing and publish a DNSKEY at the apex. Use DNSViz to validate the full chain.

p=reject

p=reject — published organizational policy. Strongest published policy (SPF/DKIM alignment still not measured here).

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

Record at _dmarc.gov.vc:

v=DMARC1; p=reject; rua=mailto:admin@gov.vc; ruf=mailto:itsd-security@gov.vc; fo=1

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