Overall IPv4-only

Collected2026-10-15 12:33 UTC

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.misk.com, ns2.misk.com.
Publish AAAA records for mail (MX): mail.smart-bz.com.
Enable DNSSEC signing and publish a DNSKEY at the apex. Use DNSViz to validate the full chain.

IPv4-only

[2] 0/0/0 [O]

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

IPv4 3/3/3 · IPv6 0/0/0 · location O

Host	IPv4	IPv6	Probes
`ns1.misk.com` [O]	142.202.38.53, 199.47.130.53	—	ipv4 142.202.38.53 ok; ipv4 199.47.130.53 ok;
`ns2.misk.com` [O]	35.236.126.148	—	ipv4 35.236.126.148 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.smart-bz.com` [I]	186.65.88.207	—	ipv4 186.65.88.207 no_banner;

📌 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

Host	IPv4	IPv6	Probes
`www.smart-bz.com` [I]	172.66.170.93, 104.20.28.6	2606:4700:10::ac42:aa5d, 2606:4700:10::6814:1c06	ipv4 ok; ipv6 ok;

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.

p=reject

p=reject — published organizational policy. Strongest published policy (SPF/DKIM alignment still not measured here).

Meaning: Published DMARC policy at _dmarc.smart-bz.com (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.

Record at _dmarc.smart-bz.com:

v=DMARC1;p=reject;pct=10;fo=1;rua=mailto:a7360bb3@mxtoolbox.dmarc-report.com;ruf=mailto:a7360bb3@forensics.dmarc-report.com

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