Problems

  • ✗
    Lame delegation
    Nameservers · These nameservers don't answer authoritatively for the zone, so resolvers ignore them: pass3.ac-guadeloupe.fr (194.57.236.1): SERVFAIL, authoritative=false.
    #15
  • ✗
    Zone transfer allowed
    Nameservers · These nameservers send the complete zone to anyone who asks (AXFR), exposing all host names: dns0.ac-martinique.fr (195.83.254.100): 636 records. Restrict zone transfers to your secondary servers.
    #18
  • ✗
    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: mona.martinique.univ-ag.fr (194.199.97.2): read tcp 46.225.38.91:43692->194.199.97.2:53: i/o timeout; pass3.ac-guadeloupe.fr (194.57.236.1): .
    #19
  • !
    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only at the parent: pass3.ac-guadeloupe.fr. dns0.ac-martinique.fr, mona.martinique.univ-ag.fr report NS dns0.ac-martinique.fr mona.martinique.univ-ag.fr.
    #7
  • !
    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: mona.martinique.univ-ag.fr: "9.4.2-P1". Hide or replace the version string.
    #17
  • !
    Unusual SOA timers
    SOA · refresh 5m is outside 20m–1d; retry 1h should be shorter than refresh 5m. Current values: refresh 5m, retry 1h, expire 7d, negative TTL 1d.
    #23
  • !
    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: 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
  • !
    No key under common selectors
    DKIM · The _domainkey name exists but no DKIM key was found under the common selectors. Selectors are provider-specific; check yours with -selector.
    #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: msg-a85.education.gouv.fr, msg-b85.education.gouv.fr
    #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.
