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

Mail
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.

📌 Action item(s):

Web
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 ok; ipv6 ok; |
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
p=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.
Record at _dmarc.gta.net:
v=DMARC1;p=quarantine;rua=mailto:secureit@gta.net;fo=1;ri=86400
Policy publication only — SPF/DKIM not measured. Not part of the 0–4 row score.
Check on dmarcian
📌 Action item(s):
- Tighten DMARC toward p=reject when ready. Review on dmarcian.
