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: ns1.oecs.org, ns2.oecs.org.
Publish AAAA records for web host: oecs.int.
Enable DNSSEC signing and publish a DNSKEY at the apex. Use DNSViz to validate the full chain.
Tighten DMARC toward p=reject when ready. Review on dmarcian.

Checks

DNS

IPv4-only

[2] 0/0/0 [O]

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 O

Host	IPv4	IPv6	Probes
`ns2.oecs.org` [O]	18.221.152.80	—	ipv4 18.221.152.80 ok;
`ns1.oecs.org` [O]	3.23.40.1	—	ipv4 3.23.40.1 ok;

📌 Action item(s):

Publish AAAA records for name server: ns1.oecs.org, ns2.oecs.org.

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

Host	IPv4	IPv6	Probes
`aspmx2.googlemail.com` [O]	74.125.137.26	2607:f8b0:4023:c03::1b	ipv4 74.125.137.26 ok; ipv6 2607:f8b0:4023:c03::1b ok;

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
`oecs.int` [I]	3.23.40.1	—	ipv4 ok;

📌 Action item(s):

Publish AAAA records for web host: oecs.int.

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.oecs.int (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.

Record at _dmarc.oecs.int:

v=DMARC1;p=quarantine;sp=quarantine;adkim=r;aspf=r;pct=100;fo=1;rf=afrf;ri=86400;rua=mailto:psy8al4w@ag.us.dmarcian.com;ruf=mailto:itsubscriptions@oecs.int

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

📌 Action item(s):

Tighten DMARC toward p=reject when ready. Review on dmarcian.
