  • ✗
    Nameservers not responding
    Nameservers · These addresses did not answer, so resolvers waste time on timeouts: ns1.uca.fr (2001:660:5102:1012::2:110): read udp [2a01:4f8:1c1c:eebf::1]:42867->[2001:660:5102:1012::2:110]:53: i/o timeout; ns2.uca.fr (2001:660:5101:1012::2:110): read udp [2a01:4f8:1c1c:eebf::1]:36440->[2001:660:5101:1012::2:110]:53: i/o timeout.

    Glue differs from the zone
    Delegation · The addresses at the parent (glue) differ from the addresses in the zone: ns1.uca.fr (glue 195.221.122.110, zone 195.221.122.110, 2001:660:5102:1012::2:110); ns2.uca.fr (glue 193.49.117.110, zone 193.49.117.110, 2001:660:5101:1012::2:110). Update the glue at your registrar.

    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.uca.fr: "9.16.23-RH"; ns2.uca.fr: "9.16.23-RH". 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

  • ✗
    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.u-clermont1.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.

    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mx1.relay.renater.fr, mx2.relay.renater.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.
