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 mail (MX): mailstore1.secureserver.net, smtp.secureserver.net.
Publish AAAA records for web host: nationalbankoftuvalu.com.
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

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
`ns52.domaincontrol.com` [O]	173.201.73.26	2603:5:2292::1a	ipv4 173.201.73.26 ok; ipv6 2603:5:2292::1a ok;
`ns51.domaincontrol.com` [O]	97.74.105.26	2603:5:2192::1a	ipv4 97.74.105.26 ok; ipv6 2603:5:2192::1a ok;

Mail

IPv4-only

[2 MX] v4 smtp 6/6/6 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 6/6/6 · IPv6 0/0/0 · location O

Host	IPv4	IPv6	Probes
`smtp.secureserver.net` [O]	216.69.141.71, 216.69.141.113, 216.69.141.84	—	ipv4 216.69.141.71 ok; ipv4 216.69.141.113 ok; ipv4 216.69.141.84 ok;
`mailstore1.secureserver.net` [O]	216.69.141.114, 216.69.141.78, 216.69.141.162	—	ipv4 216.69.141.114 ok; ipv4 216.69.141.78 ok; ipv4 216.69.141.162 ok;

📌 Action item(s):

Publish AAAA records for mail (MX): mailstore1.secureserver.net, smtp.secureserver.net.

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 2/2/2 · IPv6 0/0/0 · location I

Host	IPv4	IPv6	Probes
`nationalbankoftuvalu.com` [I]	76.223.105.230, 13.248.243.5	—	ipv4 ok;

📌 Action item(s):

Publish AAAA records for web host: nationalbankoftuvalu.com.

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.nationalbankoftuvalu.com (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.

Record at _dmarc.nationalbankoftuvalu.com:

v=DMARC1; p=quarantine; adkim=r; aspf=r; rua=mailto:dmarc_rua@onsecureserver.net;

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.
