Problems

  • !
    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: nsauth1.trans-ix.nl. nsauth1.trans-ix.nl, nsauth2.trans-ix.net, nsauth3.trans-ix.com report NS nsauth1.trans-ix.nl nsauth2.trans-ix.net nsauth3.trans-ix.com.

  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: nsauth1.trans-ix.nl: "9.18.39-0ubuntu0.22.04.7-Ubuntu"; nsauth2.trans-ix.net: "9.18.39-0ubuntu0.22.04.7-Ubuntu"; nsauth3.trans-ix.com: "9.18.30-0ubuntu0.20.04.2-Ubuntu". Hide or replace the version string.

    Unusual SOA timers
    SOA · retry 1h should be shorter than refresh 1h. Current values: refresh 1h, retry 1h, expire 14d, negative TTL 1d.

    Not signed

Problems

  • ✗
    No DKIM keys published
    DKIM · _domainkey.tcsamsterdammarathon.nl 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
  • !
    No MX records
    MX · No MX records found. If this domain is used for email, add MX records to specify mail servers. If it never receives mail, publish a null MX ("MX 0 .").
    #9
  • !
    No aggregate reports (rua)
    DMARC · DMARC record has no rua tag, so you receive no aggregate reports about who sends mail as your domain. Add rua=mailto:...
    #19
  • !
    Report address not authorized
    DMARC · These report addresses are in another domain that has not agreed to receive your reports, so receivers will not send them: mailto:rapporten@lechampion.nl (needs tcsamsterdammarathon.nl._report._dmarc.lechampion.nl). Ask the report provider to publish the record, or check the address.
