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 web host: cucgov.org.
Enable DNSSEC signing and publish a DNSKEY at the apex. Use DNSViz to validate the full chain.
DMARC is monitoring-only (p=none). Move toward quarantine, then reject. Review 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
`ns68.domaincontrol.com` [O]	173.201.71.44	2603:5:2274::2c	ipv4 173.201.71.44 ok; ipv6 2603:5:2274::2c ok;
`ns67.domaincontrol.com` [O]	97.74.103.44	2603:5:2174::2c	ipv4 97.74.103.44 ok; ipv6 2603:5:2174::2c ok;

Mail

Dual-stack

[1 MX] v4 smtp 4/4/4 v6 smtp 4/4/4 [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 4/4/4 · IPv6 4/4/4 · location O

Host	IPv4	IPv6	Probes
`cucgov-org.mail.protection.outlook.com` [O]	52.101.124.117, 52.101.157.80, 52.101.137.0, 52.101.137.2	2a01:111:f403:cc1f::4, 2a01:111:f403:cc1a::8, 2a01:111:f403:cc09::, 2a01:111:f403:cc09::1	ipv4 52.101.124.117 ok; ipv4 52.101.157.80 ok; ipv4 52.101.137.0 ok; ipv4 52.101.137.2 ok; ipv6 2a01:111:f403:cc1f::4 ok; ipv6 2a01:111:f403:cc1a::8 ok; ipv6 2a01:111:f403:cc09:: ok; ipv6 2a01:111:f403:cc09::1 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
`cucgov.org` [I]	162.159.134.42	—	ipv4 ok;

📌 Action item(s):

Publish AAAA records for web host: cucgov.org.

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.cucgov.org (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.

Record at _dmarc.cucgov.org:

v=DMARC1; p=none; rua=mailto:itcuc@cucgov.org; ruf=mailto:itcuc@cucgov.org; fo=1

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.
