    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only in the zone: ns1.renater.fr, ns2.renater.fr. soleil.uvsq.fr report NS ns1.renater.fr ns1.univ-reunion.fr ns2.renater.fr ns2.univ-reunion.fr soleil.uvsq.fr.

  • ✓ Glue present and correct #8
    Glue is published for the nameservers inside the zone: ns1.univ-reunion.fr, ns2.univ-reunion.fr.
  • ✓ All names resolve #9
    Every nameserver name has an address and is not an alias.
  • i
    One address family in one network
    all IPv6 addresses are in 2001:660:3001::/48, while the other address family is spread over several networks.
    #10
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS2200 (FR-RENATER - Renater, FR): 5 addresses; AS2470 (FR-LAREUNION - Renater, EU): 2 addresses.
  • 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: ns1.univ-reunion.fr, ns2.univ-reunion.fr, soleil.uvsq.fr.

  • ✗
    Nameservers not responding
    These addresses did not answer, so resolvers waste time on timeouts: ns1.univ-reunion.fr (195.220.150.17): read udp 46.225.38.91:40403->195.220.150.17:53: i/o timeout; ns2.univ-reunion.fr (194.199.73.30): read udp 46.225.38.91:52418->194.199.73.30:53: i/o timeout.

  • ✗
    Lame delegation
    These nameservers don't answer authoritatively for the zone, so resolvers ignore them: ns1.renater.fr (193.49.159.2): SERVFAIL, authoritative=false; ns1.renater.fr (2001:660:3001:4002::2): SERVFAIL, authoritative=false; ns2.renater.fr (193.49.159.9): SERVFAIL, authoritative=false; ns2.renater.fr (2001:660:3001:4002::9): SERVFAIL, authoritative=false.

  • ✓ 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: ns1.renater.fr (193.49.159.2): ; ns1.renater.fr (2001:660:3001:4002::2): ; ns2.renater.fr (193.49.159.9): ; ns2.renater.fr (2001:660:3001:4002::9): .
