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

Priority next steps

Web measurement was inconclusive or unavailable.
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.

Checks

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 2/2/2 · IPv6 2/2/2 · location O

Host	IPv4	IPv6	Probes
`dns101.ovh.net` [O]	5.196.38.125	2001:41d0:d00:fb00::2	ipv4 5.196.38.125 ok; ipv6 2001:41d0:d00:fb00::2 ok;
`ns101.ovh.net` [O]	5.135.53.37	2001:41d0:b00:f500::2	ipv4 5.135.53.37 ok; ipv6 2001:41d0:b00:f500::2 ok;

Mail

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 SMTP 5/5/5 · IPv6 5/5/5 · location O

Web

Unknown

[0] error: Get "https://www.saintbarthtelecom.fr/": tls: failed to verify certificate: x509: certificate is valid for cluster131.hosting.ovh.net, not www.saintbarthtelecom.fr

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.saintbarthtelecom.fr.

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

Publish a DMARC TXT at _dmarc.saintbarthtelecom.fr (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.
