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.

Mail
Dual-stack
[8 MX] v4 smtp 8/8/8 v6 smtp 4/4/4 [O]
Meaning: Shows MX footprint and SMTP health per IP family. Operational means an SMTP banner and EHLO exchange succeeded on port 25.

Web
Dual-stack
[1] 1/1/1 [I]

DMARC
p=reject
p=reject — published organizational policy. Strongest published policy (SPF/DKIM alignment still not measured here).
Meaning: Published DMARC policy at _dmarc.arcep.fr (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.
Record at _dmarc.arcep.fr:
v=DMARC1;p=reject;pct=100;rua=mailto:dmarc@arcep.fr;
Policy publication only — SPF/DKIM not measured. Not part of the 0–4 row score.
