Problems

  • ✗
    Nameservers not responding
    Nameservers · These addresses did not answer, so resolvers waste time on timeouts: ns2.seatsandsofas.nl (2a03:7900:111:0:a4fb:16ff:fe69:d48f): read udp [2a01:4f8:1c1c:eebf::1]:49172->[2a03:7900:111:0:a4fb:16ff:fe69:d48f]:53: i/o timeout.
    #14
  • ✗
    Zone transfer allowed
    Nameservers · These nameservers send the complete zone to anyone who asks (AXFR), exposing all host names: ns2.seatsandsofas.nl (31.3.110.162): 250 records. Restrict zone transfers to your secondary servers.
    #18
  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns.seatsandsofas.nl: "9.18.39-0ubuntu0.22.04.7-Ubuntu"; ns2.seatsandsofas.nl: "9.18.12-0ubuntu0.22.04.3-Ubuntu". Hide or replace the version string.
    #17
  • !
    Serials differ
    SOA · The nameservers serve different versions of the zone: 2026073224 on ns.seatsandsofas.nl (87.213.98.178); 2026073441 on ns2.seatsandsofas.nl (31.3.110.162). This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.
    #22
  • !
    Signed but not delegated securely
    DNSSEC · The zone is signed but the parent has no DS record, so the signatures are not used. Publish the DS record at your registrar.
    #27
  • !
    Signatures expire soon
    DNSSEC · The earliest signature expires at 2026-10-28 17:21 UTC (in 146h0m0s). Check that automatic re-signing works.

Problems

  • ✗
    Policy: none (monitoring only)
    DMARC · DMARC policy is set to 'none', which only monitors but doesn't protect against spoofing. Consider upgrading to 'quarantine' or ideally 'reject'.
    #4
  • !
    Signed, but no DS at parent
    DNSSEC · The zone is signed (DNSKEY present) but the parent has no DS record, so the chain of trust is incomplete. Publish the DS record at your registrar.
    #8
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mail.seatsandsofas.nl
    #11
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    Signatures expire in 146h0m0s
    DNSSEC · DNSKEY signatures expire at 2026-10-28T17:21:47Z (in 146h0m0s). Check that re-signing works.
    #21
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: default (1024 bits), mail (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    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.
