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: dacnis.univ-guyane.fr, daknis.univ-guyane.fr.
Publish AAAA records for mail (MX): mx1.relay.renater.fr, mx2.relay.renater.fr.
Publish AAAA records for web host: www.univ-guyane.fr.
Enable DNSSEC signing and publish a DNSKEY at the apex. Use DNSViz to validate the full chain.

IPv4-only

[2] 0/0/0 [I]

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

IPv4 2/2/2 · IPv6 0/0/0 · location I

Host	IPv4	IPv6	Probes
`dacnis.univ-guyane.fr` [I]	193.48.162.3	—	ipv4 193.48.162.3 ok;
`daknis.univ-guyane.fr` [I]	193.48.162.5	—	ipv4 193.48.162.5 ok;

📌 Action item(s):

Publish AAAA records for name server: dacnis.univ-guyane.fr, daknis.univ-guyane.fr.

IPv4-only

[2 MX] v4 smtp 2/2/2 v6 smtp 0/0/0 [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 2/2/2 · IPv6 0/0/0 · location O

Host	IPv4	IPv6	Probes
`mx2.relay.renater.fr` [O]	85.31.212.203	—	ipv4 85.31.212.203 ok;
`mx1.relay.renater.fr` [O]	85.31.212.3	—	ipv4 85.31.212.3 ok;

📌 Action item(s):

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
`www.univ-guyane.fr` [I]	193.48.162.160	—	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.

p=reject

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

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

Record at _dmarc.univ-guyane.fr:

v=DMARC1; p=reject; pct=100; ruf=mailto:dmarc-ruf@univ-guyane.fr; rua=mailto:dmarc-rua@univ-guyane.fr;

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