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 name server: ns23-131.tstt.net.tt, ns28.tstt.net.tt.
Publish AAAA records for mail (MX): mx.etenderworld.tt.
Publish AAAA records for web host: bmobile.co.tt.
Enable DNSSEC signing and publish a DNSKEY at the apex. Use DNSViz to validate the full chain.
Tighten DMARC toward p=reject when ready. Review on dmarcian.

Checks

DNS

IPv4-only

[2] 0/0/0 [O]

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

IPv4 2/2/2 · IPv6 0/0/0 · location O

Host	IPv4	IPv6	Probes
`ns28.tstt.net.tt` [O]	196.3.132.28	—	ipv4 196.3.132.28 ok;
`ns23-131.tstt.net.tt` [O]	190.58.23.131	—	ipv4 190.58.23.131 ok;

📌 Action item(s):

Publish AAAA records for name server: ns23-131.tstt.net.tt, ns28.tstt.net.tt.

Mail

IPv4-only

[1 MX] v4 smtp 1/1/1 v6 smtp 0/0/0 [O]

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 O

Host	IPv4	IPv6	Probes
`mx.etenderworld.tt` [O]	190.58.160.85	—	ipv4 190.58.160.85 ok;

📌 Action item(s):

Publish AAAA records for mail (MX): mx.etenderworld.tt.

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
`bmobile.co.tt` [I]	190.58.160.98	—	ipv4 ok;

📌 Action item(s):

Publish AAAA records for web host: bmobile.co.tt.

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

p=quarantine, sp=none

p=quarantine, sp=none — published organizational policy. Ask receivers to quarantine failing mail; reject is stronger.

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

Record at _dmarc.bmobile.co.tt:

v=DMARC1; p=quarantine; sp=none; adkim=r; aspf=r; rf= afrf; rua=mailto:dmarc@bmobile.co.tt; ruf=mailto:dmarc@bmobile.co.tt

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