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

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 ok; |
📌 Action item(s):
- Publish AAAA records for web host: gov.nu.
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
No record
No record — no TXT at _dmarc.gov.nu.
Meaning: Published DMARC policy at _dmarc.gov.nu (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.
Publish a DMARC TXT at _dmarc.gov.nu (often start with p=none, then tighten).
Policy publication only — SPF/DKIM not measured. Not part of the 0–4 row score.
Check on dmarcian
📌 Action item(s):
- Publish a _dmarc TXT record (start with p=none, then tighten). Check policy on dmarcian.
