Web
IPv4-only
[1] 0/0/0 [I]

📌 Action item(s):
- Publish AAAA records for web host: gov.vu.
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.

DMARC
No record
No record — no TXT at _dmarc.gov.vu.
Meaning: Published DMARC policy at _dmarc.gov.vu (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.
Publish a DMARC TXT at _dmarc.gov.vu (often start with p=none, then tighten).
Policy publication only — SPF/DKIM not measured. Not part of the 0–4 row score.
