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

Priority next steps

IPv6 probe for web host minowc.sr failed (http_5xx) — check firewall, routing, and service.
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.

Dual-stack

[2] 6/6/6 [O]

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

Dual-stack

[5 MX] v4 smtp 5/5/5 v6 smtp 5/5/5 [O]

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

IPv4-only

[1] 2/2/0 [I]

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

`minowc.sr` [I]	172.67.184.210, 104.21.59.227	2606:4700:3030::ac43:b8d2, 2606:4700:3034::6815:3be3	ipv4 http_5xx; ipv6 http_5xx;

📌 Action item(s):

IPv6 probe for web host minowc.sr failed (http_5xx) — check firewall, routing, and service.

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.minowc.sr.

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

Publish a DMARC TXT at _dmarc.minowc.sr (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.
