Problems

  • ✗
    Nameserver names don't resolve
    Delegation · These nameservers have no A or AAAA record, so they can't be reached (lame delegation): ns3.aquitaine.fr.
    #9
  • ✗
    Nameservers not responding
    Nameservers · These addresses did not answer, so resolvers waste time on timeouts: ns2.ac-bordeaux.fr (194.199.36.116): read udp 46.225.38.91:43081->194.199.36.116:53: i/o timeout.
    #14
  • ✗
    Lame delegation
    Nameservers · These nameservers don't answer authoritatively for the zone, so resolvers ignore them: dns1.ac-toulouse.fr (194.214.239.1): SERVFAIL, authoritative=false; dns2.ac-toulouse.fr (194.214.239.2): SERVFAIL, authoritative=false.
    #15
  • ✗
    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: dns1.ac-toulouse.fr (194.214.239.1): ; dns2.ac-toulouse.fr (194.214.239.2): .
    #19
  • !
    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only at the parent: camus.dr15.cnrs.fr, dns1.ac-bordeaux.fr, ns3.aquitaine.fr; only in the zone: ns1.ac-bordeaux.fr, ns2.ac-bordeaux.fr. camus.dr15.cnrs.fr, dns1.ac-bordeaux.fr, ns1.ac-bordeaux.fr report NS dns1.ac-toulouse.fr dns2.ac-toulouse.fr ns1.ac-bordeaux.fr ns2.ac-bordeaux.fr.
    #7
  • !
    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"; ns1.ac-bordeaux.fr: "9.9.4-RedHat-9.9.4-61.el7". 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

  • !
    Policy: quarantine
    DMARC · DMARC policy is set to 'quarantine'. Consider upgrading to 'reject' for stronger protection once you've verified legitimate emails are passing authentication.
    #4
  • !
    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: default (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.
