Measurement estimates from a single vantage point — not a compliance certification. Guidance below is for operators, not an SLA.
DNS
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 |
poseidon.unc.nc [I] |
194.254.189.29 |
— |
ipv4 194.254.189.29 ok; |
chronos.unc.nc [I] |
194.254.189.30 |
— |
ipv4 194.254.189.30 ok; |
📌 Action item(s):
- Publish AAAA records for name server: chronos.unc.nc, poseidon.unc.nc.
Mail
IPv4-only
[1 MX] v4 smtp 1/1/1 v6 smtp 0/0/0 [I]
Meaning: Shows MX footprint and SMTP health per IP family. Operational means an SMTP banner and EHLO exchange succeeded on port 25.
IPv4 SMTP 1/1/1 · IPv6 0/0/0 · location I
| Host | IPv4 | IPv6 | Probes |
mx1.unc.nc [I] |
194.254.189.42 |
— |
ipv4 194.254.189.42 ok; |
📌 Action item(s):
- Publish AAAA records for mail (MX): mx1.unc.nc.
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.unc.nc [I] |
194.254.189.35 |
— |
ipv4 ok; |
📌 Action item(s):
- Publish AAAA records for web host: www.unc.nc.
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=quarantine
p=quarantine — published organizational policy. Ask receivers to quarantine failing mail; reject is stronger.
Meaning: Published DMARC policy at _dmarc.unc.nc (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.
Record at _dmarc.unc.nc:
v=DMARC1; p=quarantine; pct=100; rua=mailto:dmarc.agg@unc.nc; ruf=mailto:dmarc.for@unc.nc; fo=1; adkim=s; aspf=r; ri=86400
Policy publication only — SPF/DKIM not measured. Not part of the 0–4 row score.
Check on dmarcian
📌 Action item(s):
- Tighten DMARC toward p=reject when ready. Review on dmarcian.
