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: hainet.net.
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] 6/6/6 [O]

Meaning: Shows how many authoritative name servers exist, and how many IPv6 endpoints are configured, responsive, and operational.

IPv4 6/6/6 · IPv6 6/6/6 · location O

Host	IPv4	IPv6	Probes
`chin.ns.cloudflare.com` [O]	173.245.58.84, 172.64.32.84, 108.162.192.84	2a06:98c1:50::ac40:2054, 2803:f800:50::6ca2:c054, 2606:4700:50::adf5:3a54	ipv4 173.245.58.84 ok; ipv4 172.64.32.84 ok; ipv4 108.162.192.84 ok; ipv6 2a06:98c1:50::ac40:2054 ok; ipv6 2803:f800:50::6ca2:c054 ok; ipv6 2606:4700:50::adf5:3a54 ok;

Mail

Dual-stack

[5 MX] v4 smtp 5/5/5 v6 smtp 5/5/5 [O]

Meaning: Shows MX footprint and SMTP health per IP family. Operational means an SMTP banner and EHLO exchange succeeded on port 25.

Web

IPv4-only

[1] 0/0/0 [O]

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 O

Host	IPv4	IPv6	Probes
`hainet.net` [O]	31.97.136.5	—	ipv4 ok;

📌 Action item(s):

Publish AAAA records for web host: hainet.net.

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.hainet.ht (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.

Record at _dmarc.hainet.ht:

v=DMARC1;p=none;rua=mailto:abuse@hainet.ht;ruf=mailto:abuse@hainet.ht;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.
