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.bna.cw, ns2.bna.cw.
Publish AAAA records for mail (MX): mail3.uts.cw.
Web measurement was inconclusive or unavailable.
Enable DNSSEC signing and publish a DNSKEY at the apex. Use DNSViz to validate the full chain.

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.bna.cw` [O]	216.122.189.86	—	ipv4 216.122.189.86 ok;
`ns1.bna.cw` [O]	216.122.189.85	—	ipv4 216.122.189.85 ok;

📌 Action item(s):

Publish AAAA records for name server: ns1.bna.cw, ns2.bna.cw.

Mail

IPv4-only

[1 MX] v4 smtp 1/1/0 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 1/1/0 · IPv6 0/0/0 · location I

Host	IPv4	IPv6	Probes
`mail3.uts.cw` [I]	216.152.174.123	—	ipv4 216.152.174.123 timeout;

📌 Action item(s):

Publish AAAA records for mail (MX): mail3.uts.cw.

Web

Unknown

[0] error: Get "https://www.uts.cw/": tls: failed to verify certificate: x509: certificate has expired or is not yet valid: current time 2026-10-14T08:33:49Z is after 2024-07-17T21:13:28Z

Meaning: Shows IPv6 web endpoint readiness for the discovered HTTPS host. Operational means family-specific HTTPS requests complete successfully.

IPv4 0/0/0 · IPv6 0/0/0 · location -

📌 Action item(s):

Web measurement was inconclusive or unavailable.

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=reject

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

Meaning: Published DMARC policy at _dmarc.uts.cw (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.

Record at _dmarc.uts.cw:

v=DMARC1; p=reject; rua=mailto:dmarc_agg@vali.email,mailto:dmarc@uts.cw; ruf=mailto:dmarc@uts.cw

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