    NS sets differ
    The nameservers at the parent and in the zone should be the same.

  • ✓ Glue present and correct #8
    Glue is published for the nameservers inside the zone: dns1.ac-bordeaux.fr.
  • ✗
    Nameserver names don't resolve
    These nameservers have no A or AAAA record, so they can't be reached (lame delegation): ns3.aquitaine.fr.
    #9
  • ✓ Nameservers in different networks #10
    The nameservers are spread over 4 IPv4 /24s and 1 IPv6 /48.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS2200 (FR-RENATER - Renater, FR): 6 addresses; AS2202 (FR-RENATER-REAUMUR - Renater, EU): 1 address.
  • i
    All nameserver names under .fr
    All nameserver names are under one TLD, so a problem with that TLD also makes the nameservers unreachable. Some operators use names under two TLDs for extra resilience.
    #12
  • i
    Partly IPv6
    These nameservers have no IPv6 address: dns1.ac-bordeaux.fr, dns1.ac-toulouse.fr, dns2.ac-toulouse.fr, ns1.ac-bordeaux.fr, ns2.ac-bordeaux.fr.

Checks

  • ✗
    Nameservers not responding
    These addresses did not answer, so resolvers waste time on timeouts: ns2.ac-bordeaux.fr (194.199.36.116): read udp 46.225.38.91:43081->194.199.36.116:53: i/o timeout.
    #14
  • ✗
    Lame delegation
    These nameservers don't answer authoritatively for the zone, so resolvers ignore them: dns1.ac-toulouse.fr (194.214.239.1): SERVFAIL, authoritative=false; dns2.ac-toulouse.fr (194.214.239.2): SERVFAIL, authoritative=false.
    #15
  • ✓ No recursion #16
    The nameservers do not answer recursive queries for other domains.
  • !
    Software version disclosed
    These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: dns1.ac-bordeaux.fr: "9.9.4-RedHat-9.9.4-61.el7"; ns1.ac-bordeaux.fr: "9.9.4-RedHat-9.9.4-61.el7". Hide or replace the version string.
    #17
  • ✓ Zone transfers refused #18
    No nameserver allows a zone transfer to the public.
  • ✗
    No DNS over TCP
    DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: dns1.ac-toulouse.fr (194.214.239.1): ; dns2.ac-toulouse.fr (194.214.239.2): .
    #19
  • ✓ EDNS supported #20
    All nameservers support EDNS(0).
  • ✓ Public addresses #21
    All nameserver addresses are publicly routable.
