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 / enable IPv6 on MX hosts.
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.

Host-level detail (NS/MX/web addresses and probe outcomes) appears after the next collector run (v0.4+).

Dual-stack

[4] 4/4/4 [O]

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

IPv4 4/4/4 · IPv6 4/4/4 · location O

IPv4-only

[2 MX] v4 smtp 2/2/2 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 2/2/2 · IPv6 0/0/0 · location O

📌 Action item(s):

Dual-stack

[1] 2/2/2 [I]

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

IPv4 2/2/2 · IPv6 2/2/2 · location I

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.

quarantine

quarantine — published organizational policy. Ask receivers to quarantine failing mail; reject is stronger.

Meaning: Published DMARC policy at _dmarc.gta.net (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.
