    No DNS over TCP
    Nameservers · DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: ns018-4s6t3ijenvjg1143.4.d-53.jp (2001:240:bb81::29:1109): read tcp [2a01:4f8:1c1c:eebf::1]:40216->[2001:240:bb81::29:1109]:53: read: connection reset by peer; ns018-4s6t3ijenvjg1143.4.d-53.org (2001:240:bb81::29:109): read tcp [2a01:4f8:1c1c:eebf::1]:38184->[2001:240:bb81::29:109]:53: read: connection reset by peer.

    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns018-4s6t3ijenvjg1143.4.d-53.jp: "2026.10.8". Hide or replace the version string.
    #17
  • !
    Not signed
    DNSSEC · The zone is not signed with DNSSEC, so answers can be spoofed. Enable DNSSEC at your DNS provider and publish the DS record at your registrar.

Problems

  • ✗
    No DMARC record
    DMARC · No DMARC record was found for this domain. DMARC is essential for preventing email spoofing. Add a DMARC record with p=reject or at least p=quarantine.
    #5
  • ✗
    No SPF record
    SPF · No SPF record was found for this domain. SPF is important for preventing email spoofing. Add an SPF record to specify which servers are authorized to send email for your domain.
    #6
  • ✗
    No DKIM keys published
    DKIM · _domainkey.nipponsteel.com does not exist (NXDOMAIN), so no DKIM keys are published. DKIM helps prevent email spoofing. Configure DKIM with your email service provider.
    #7
  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: primary.ap.email.fireeyecloud.com, alt1.ap.email.fireeyecloud.com, alt2.ap.email.fireeyecloud.com, alt3.ap.email.fireeyecloud.com
    #11
  • !
    Not configured
    TLS · MTA-STS is not configured, so other mail servers fall back to unencrypted delivery when TLS fails or is stripped by an attacker. Publish a _mta-sts TXT record and a policy at https://mta-sts.<domain>/.well-known/mta-sts.txt.
