Problems

  • ✗
    Nameservers not responding
    Nameservers · These addresses did not answer, so resolvers waste time on timeouts: alize4.cid.msh-paris.fr (193.49.20.221): read udp 46.225.38.91:34789->193.49.20.221:53: read: connection refused.
    #14
  • !
    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only at the parent: alize4.cid.msh-paris.fr. alize.msh-paris.fr, kirova.pmsh.msh-paris.fr, ns6.gandi.net report NS alize.msh-paris.fr kirova.pmsh.msh-paris.fr ns6.gandi.net.
    #7
  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: alize.msh-paris.fr: "9.10.6-P1"; kirova.pmsh.msh-paris.fr: "9.10.3-P4". Hide or replace the version string.
    #17
  • !
    Unusual SOA timers
    SOA · retry 1h should be shorter than refresh 1h; expire 1h is shorter than 7d; secondaries stop answering too soon when the primary is down; expire 1h must be longer than refresh + retry. Current values: refresh 1h, retry 1h, expire 1h, negative TTL 1h.
    #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 high TTLs
    Records · These records have a TTL above 7d, so changes take very long to reach everyone: MX (14d), NS (14d). The NS TTL at the parent is 1h and in the zone 14d; 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
  • ✗
    No SPF record
    SPF · No SPF record was found for this domain. SPF is important for preventing email spoofing. Add an SPF record to specify which servers are authorized to send email for your domain.
    #6
  • ✗
    No DKIM keys published
    DKIM · _domainkey.lcdpu.fr 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
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mx.lcdpu.fr
    #11
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    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.
