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

Priority next steps

DNS measurement was inconclusive or unavailable.
Publish AAAA records for mail (MX): pmo-to.in.tmes-anz.trendmicro.com.
Web measurement was inconclusive or unavailable.
Enable DNSSEC signing and publish a DNSKEY at the apex. Use DNSViz to validate the full chain.

Checks

DNS

Unknown

[0] -/-/- [-]

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

IPv4 0/0/0 · IPv6 0/0/0 · location -

📌 Action item(s):

DNS measurement was inconclusive or unavailable.

Mail

IPv4-only

[1 MX] v4 smtp 3/3/3 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 3/3/3 · IPv6 0/0/0 · location O

Host	IPv4	IPv6	Probes
`pmo-to.in.tmes-anz.trendmicro.com` [O]	13.238.202.142, 13.238.202.141, 13.238.202.140	—	ipv4 13.238.202.142 ok; ipv4 13.238.202.141 ok; ipv4 13.238.202.140 ok;

📌 Action item(s):

Publish AAAA records for mail (MX): pmo-to.in.tmes-anz.trendmicro.com.

Web

Unknown

[0] error: Get "https://www.revenue.gov.to/": tls: failed to verify certificate: x509: certificate signed by unknown authority

Meaning: Shows IPv6 web endpoint readiness for the discovered HTTPS host. Operational means family-specific HTTPS requests complete successfully.

IPv4 0/0/0 · IPv6 0/0/0 · location -

📌 Action item(s):

Web measurement was inconclusive or unavailable.

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=reject

p=reject — published organizational policy. Strongest published policy (SPF/DKIM alignment still not measured here).

Meaning: Published DMARC policy at _dmarc.revenue.gov.to (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.

Record at _dmarc.revenue.gov.to:

v=DMARC1; p=reject; rua=mailto:pmo-to@dmarcrua.tmes-anz.trendmicro.com; ruf=mailto:pmo-to@dmarcrua.tmes-anz.trendmicro.com; adkim=r; aspf=r; fo=0:1:d:s; rf=afrf

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