Measurement estimates from a single vantage point — not a compliance certification. Guidance below is for operators, not an SLA.
DNS
Dual-stack
[2] 2/2/2 [O]
Meaning: Shows how many authoritative name servers exist, and how many IPv6 endpoints are configured, responsive, and operational.
IPv4 10/10/10 · IPv6 2/2/2 · location O
| Host | IPv4 | IPv6 | Probes |
darren.dnspod.net [O] |
111.206.98.235, 1.12.0.1, 1.13.76.35, 36.155.149.35, 101.227.168.35 |

Mail
Unknown
[0] -/-/- [-]
Meaning: Shows MX footprint and SMTP health per IP family. Operational means an SMTP banner and EHLO exchange succeeded on port 25.
No MX — intentionally N/A for this domain.
Web
Unknown
[0] error: Get "https://www.flowsvg.com/": dial tcp: lookup www.flowsvg.com on 185.12.64.2:53: no such host
Meaning: Shows IPv6 web endpoint readiness for the discovered HTTPS host. Operational means family-specific HTTPS requests complete successfully.
IPv4 0/0/0 · IPv6 0/0/0 · location -
📌 Action item(s):
- Web measurement was inconclusive or unavailable.
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
No record
No record — no TXT at _dmarc.flowsvg.com.
Meaning: Published DMARC policy at _dmarc.flowsvg.com (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.
Publish a DMARC TXT at _dmarc.flowsvg.com (often start with p=none, then tighten).
Policy publication only — SPF/DKIM not measured. Not part of the 0–4 row score.
Check on dmarcian
📌 Action item(s):
- Publish a _dmarc TXT record (start with p=none, then tighten). Check policy on dmarcian.
