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.relatable.host, ns2.relatable.host.
Publish AAAA records for web host: www.sjpi.edu.bb.
Enable DNSSEC signing and publish a DNSKEY at the apex. Use DNSViz to validate the full chain.
Publish a _dmarc TXT record (start with p=none, then tighten). Check policy on dmarcian.

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.relatable.host` [O]	162.240.18.19	—	ipv4 162.240.18.19 ok;
`ns1.relatable.host` [O]	162.240.17.254	—	ipv4 162.240.17.254 ok;

📌 Action item(s):

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.

Host	IPv4	IPv6	Probes
`sjpi-edu-bb.mail.protection.outlook.com` [O]	52.101.194.167, 52.101.40.28, 52.101.40.0, 52.101.50.1	2a01:111:f403:f90a::4, 2a01:111:f403:f900::1, 2a01:111:f403:c902::2, 2a01:111:f403:f913::2	ipv4 52.101.194.167 ok; ipv4 52.101.40.28 ok; ipv4 52.101.40.0 ok; ipv4 52.101.50.1 ok; ipv6 2a01:111:f403:f90a::4 ok; ipv6 2a01:111:f403:f900::1 ok; ipv6 2a01:111:f403:c902::2 ok; ipv6 2a01:111:f403:f913::2 ok;

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

`www.sjpi.edu.bb` [I]	162.240.17.254	—	ipv4 ok;

📌 Action item(s):

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.

📌 Action item(s):

Enable DNSSEC signing and publish a DNSKEY at the apex. Use DNSViz to validate the full chain.

No record

No record — no TXT at _dmarc.sjpi.edu.bb.

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

Publish a DMARC TXT at _dmarc.sjpi.edu.bb (often start with p=none, then tighten).

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

📌 Action item(s):

Publish a _dmarc TXT record (start with p=none, then tighten). Check policy on dmarcian.
