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: ns1.supercp.com, ns2.supercp.com, ns3.supercp.com, ns4.supercp.com.
Publish AAAA records for web host: cq-link.sr.
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

[4] 0/0/0 [O]

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

IPv4 4/4/4 · IPv6 0/0/0 · location O

Host	IPv4	IPv6	Probes
`ns2.supercp.com` [O]	75.2.118.134	—	ipv4 75.2.118.134 ok;

`ns1.supercp.com` [O]	13.248.158.180	—	ipv4 13.248.158.180 ok;

📌 Action item(s):

Publish AAAA records for name server: ns1.supercp.com, ns2.supercp.com, ns3.supercp.com, ns4.supercp.com.

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] 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
`cq-link.sr` [I]	68.66.216.13	—	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.cq-link.sr.

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

Publish a DMARC TXT at _dmarc.cq-link.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.
