Measurement estimates from a single vantage point — not a compliance certification. Guidance below is for operators, not an SLA.
DNS
IPv4-only
[4] 0/0/0 [I]
Meaning: Shows how many authoritative name servers exist, and how many IPv6 endpoints are configured, responsive, and operational.

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

ttconnect.gov.tt [I] |

📌 Action item(s):
- Publish AAAA records for web host: ttconnect.gov.tt.
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
SERVFAIL
SERVFAIL
Meaning: Published DMARC policy at _dmarc.gov.tt (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.
Policy publication only — SPF/DKIM not measured. Not part of the 0–4 row score.
Check on dmarcian
📌 Action item(s):
- DMARC lookup failed — re-check _dmarc TXT (dmarcian inspector can help).
