Measurement estimates from a single vantage point — not a compliance certification. Guidance below is for operators, not an SLA.

Priority next steps

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
`ns71.domaincontrol.com` [O]	97.74.105.46	2603:5:2194::2e	ipv4 97.74.105.46 ok; ipv6 2603:5:2194::2e ok;
`ns72.domaincontrol.com` [O]	173.201.73.46	2603:5:2294::2e	ipv4 173.201.73.46 ok; ipv6 2603:5:2294::2e 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
`bahamas-com.mail.protection.outlook.com` [O]	52.101.41.122, 52.101.41.28, 52.101.10.1, 52.101.9.11	2a01:111:f403:c95d::8, 2a01:111:f403:f90a::, 2a01:111:f403:c91d::b, 2a01:111:f403:c946::1c	ipv4 52.101.41.122 ok; ipv4 52.101.41.28 ok; ipv4 52.101.10.1 ok; ipv4 52.101.9.11 ok; ipv6 2a01:111:f403:c95d::8 ok; ipv6 2a01:111:f403:f90a:: ok; ipv6 2a01:111:f403:c91d::b ok; ipv6 2a01:111:f403:c946::1c ok;

Web

Dual-stack

[1] 5/5/5 [I]

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

IPv4 5/5/5 · IPv6 5/5/5 · location I

Host	IPv4	IPv6	Probes
`www.bahamas.com` [I]	104.18.163.83, 104.18.161.83, 104.18.164.83, 104.18.162.83, 104.18.160.83	2606:4700::6812:a353, 2606:4700::6812:a053, 2606:4700::6812:a153, 2606:4700::6812:a453, 2606:4700::6812:a253	ipv4 ok; ipv6 ok;

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

Record at _dmarc.bahamas.com:

v=DMARC1; p=none;

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