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: ns.itcenter.gov.ag.
Publish AAAA records for mail (MX): mail.customs.gov.ag.
Publish AAAA records for web host: customs.gov.ag.
Enable DNSSEC signing and publish a DNSKEY at the apex. Use DNSViz to validate the full chain.
Publish a _dmarc TXT record (start with p=none, then tighten). Check policy on dmarcian.

IPv4-only

[1] 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
`ns.itcenter.gov.ag` [O]	69.50.74.40, 69.57.244.180	—	ipv4 69.50.74.40 ok; ipv4 69.57.244.180 ok;

📌 Action item(s):

IPv4-only

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

Meaning: Shows MX footprint and SMTP health per IP family. Operational means an SMTP banner and EHLO exchange succeeded on port 25.

IPv4 SMTP 1/1/0 · IPv6 0/0/0 · location I

Host	IPv4	IPv6	Probes
`mail.customs.gov.ag` [I]	69.57.244.159	—	ipv4 69.57.244.159 timeout;

📌 Action item(s):

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
`customs.gov.ag` [I]	20.185.58.211	—	ipv4 ok;

📌 Action item(s):

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.

📌 Action item(s):

Enable DNSSEC signing and publish a DNSKEY at the apex. Use DNSViz to validate the full chain.

No record

No record — no TXT at _dmarc.customs.gov.ag.

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

Publish a DMARC TXT at _dmarc.customs.gov.ag (often start with p=none, then tighten).

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

📌 Action item(s):

Publish a _dmarc TXT record (start with p=none, then tighten). Check policy on dmarcian.
