Problems

  • !
    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: soleil.uvsq.fr. bievre.univ-paris3.fr, lendit.univ-paris3.fr, soleil.uvsq.fr report NS bievre.univ-paris3.fr lendit.univ-paris3.fr soleil.uvsq.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: bievre.univ-paris3.fr: "DNS Service for Microsoft Windows 3.11"; lendit.univ-paris3.fr: "DNS Service for Microsoft Windows 3.11". Hide or replace the version string.
    #17
  • !
    Unusual SOA timers
    SOA · retry 1h should be shorter than refresh 1h. Current values: refresh 1h, retry 1h, expire 1000h, 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.
    #27
  • !
    Very low TTLs
    Records · These records have a TTL below 5m, causing extra queries and slower lookups: MX (1m), NS (1m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 1m; resolvers may use either.

Problems

  • ✗
    No DMARC record
    DMARC · No DMARC record was found for this domain. DMARC is essential for preventing email spoofing. Add a DMARC record with p=reject or at least p=quarantine.
    #5
  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    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.
