Problems

  • ✗
    Nameservers not responding
    Nameservers · These addresses did not answer, so resolvers waste time on timeouts: ns1.bmgroup.be (2a01:4f8:221:ac4::3): read udp [2a01:4f8:1c1c:eebf::1]:50700->[2a01:4f8:221:ac4::3]:53: read: permission denied; ns2.serverpark.be (2a01:4f8:221:ac4::4): read udp [2a01:4f8:1c1c:eebf::1]:60644->[2a01:4f8:221:ac4::4]:53: read: permission denied.

  • ✗
    Zone transfer allowed
    Nameservers · These nameservers send the complete zone to anyone who asks (AXFR), exposing all host names: ns1.serverpark.be (176.9.35.17): 42 records; ns1.serverpark.be (2a01:4f8:150:4108::3): 42 records; ns2.bmgroup.be (176.9.35.17): 42 records; ns2.bmgroup.be (2a01:4f8:150:4108::4): 42 records. Restrict zone transfers to your secondary servers.

  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.bmgroup.be: "PowerDNS Authoritative Server 3.4.11 (jenkins@autotest.powerdns.com built 20170116223245 mockbuild@buildhw-05.phx2.fedoraproject.org)"; ns1.serverpark.be: "PowerDNS Authoritative Server 3.3.3 (jenkins@autotest.powerdns.com built 20161031213210 mockbuild@)"; ns2.bmgroup.be: "PowerDNS Authoritative Server 3.3.3 (jenkins@autotest.powerdns.com built 20161031213210 mockbuild@)"; ns2.serverpark.be: "PowerDNS Authoritative Server 3.4.11 (jenkins@autotest.powerdns.com built 20170116223245 mockbuild@buildhw-05.phx2.fedoraproject.org)". Hide or replace the version string.
    #17
  • !
    Unusual SOA timers
    SOA · expire 5d is shorter than 7d; secondaries stop answering too soon when the primary is down. Current values: refresh 50m, retry 20m, expire 5d, 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.

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
  • !
    Uses deprecated ptr mechanism
    SPF · The ptr mechanism in SPF records is deprecated due to performance issues and should be avoided.
    #1
  • !
    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
  • !
    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.
