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 [O]
Meaning: Shows how many authoritative name servers exist, and how many IPv6 endpoints are configured, responsive, and operational.
IPv4 4/4/4 · IPv6 0/0/0 · location O
| Host | IPv4 | IPv6 | Probes |
|---|
dns7.gov.tt [O] |
190.58.156.91 |
— |
ipv4 190.58.156.91 ok; |
dns6.gov.tt [O] |
190.58.156.108 |
— |
ipv4 190.58.156.108 ok; |
dns8.gov.tt [O] |
190.58.156.109 |
— |
ipv4 190.58.156.109 ok; |
dns5.gov.tt [O] |
190.58.156.90 |
— |
ipv4 190.58.156.90 ok; |
📌 Action item(s):
- Publish AAAA records for name server: dns5.gov.tt, dns6.gov.tt, dns7.gov.tt, dns8.gov.tt.
Mail
Unknown
[0] -/-/- [-]
Meaning: Shows MX footprint and SMTP health per IP family. Operational means an SMTP banner and EHLO exchange succeeded on port 25.
No MX — intentionally N/A for this domain.
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 |
|---|
ttconnect.gov.tt [I] |
52.255.202.66 |
— |
ipv4 ok; |
📌 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.

DMARC
SERVFAIL
SERVFAIL
Meaning: Published DMARC policy at _dmarc.ttconnect.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).
