Problems

  • ✗
    Nameserver names are CNAMEs
    Delegation · Nameserver names must not be aliases (RFC 2181 10.3): dns1.ac-bordeaux.fr -> ns1.ac-bordeaux.fr.
    #9
  • !
    No IPv6
    Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13
  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: dns1.ac-bordeaux.fr: "9.9.4-RedHat-9.9.4-61.el7". Hide or replace the version string.
    #17
  • !
    Serials differ
    SOA · The nameservers serve different versions of the zone: 2026063000 on dns1.ac-bordeaux.fr (194.199.33.1); 2026091700 on dns1.ac-toulouse.fr (194.214.239.1), dns2.ac-toulouse.fr (194.214.239.2). This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.
    #22
  • !
    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.
    #27

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
  • !
    Ends with ?all (neutral)
    SPF · SPF record uses ?all (neutral), which gives no protection against unauthorized senders. Use -all or ~all instead.
    #3
  • !
    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: msg-a85.education.gouv.fr, msg-b85.education.gouv.fr
    #11
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: 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.
