Measurement estimates from a single vantage point — not a compliance certification. Guidance below is for operators, not an SLA.
DNS
Dual-stack
[3] 1/1/1 [M]
Meaning: Shows how many authoritative name servers exist, and how many IPv6 endpoints are configured, responsive, and operational.
IPv4 3/3/3 · IPv6 1/1/1 · location M
| Host | IPv4 | IPv6 | Probes |
|---|
draco.upf.pf [I] |
194.214.253.247 |
— |
ipv4 194.214.253.247 ok; |
osiris.lip6.fr [O] |
132.227.60.30 |
2001:660:3302:283c::1e |
ipv4 132.227.60.30 ok; ipv6 2001:660:3302:283c::1e ok; |
soleil.uvsq.fr [O] |
193.51.24.1 |
— |
ipv4 193.51.24.1 ok; |
📌 Action item(s):
- Publish AAAA records for name server: draco.upf.pf, soleil.uvsq.fr.
Mail
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):
- Publish AAAA records for mail (MX): mx1.relay.renater.fr, mx2.relay.renater.fr.
Web
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.upf.pf [I] |
194.214.253.178 |
— |
ipv4 ok; |
📌 Action item(s):
- Publish AAAA records for web host: www.upf.pf.
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
p=none
p=none — published organizational policy. Monitoring only (receivers should not reject mail); tighten toward quarantine, then reject when ready. Not the same as missing DMARC.
Meaning: Published DMARC policy at _dmarc.upf.pf (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.
Record at _dmarc.upf.pf:
v=DMARC1; p=none; sp=none; adkim=r; aspf=r; pct=100; fo=1; rf=afrf; ri=86400; rua=mailto:dmarc@relay.renater.fr; ruf=mailto:dmarc@relay.renater.fr
Policy publication only — SPF/DKIM not measured. Not part of the 0–4 row score.
Check on dmarcian
📌 Action item(s):
- DMARC is monitoring-only (p=none). Move toward quarantine, then reject. Review on dmarcian.
