    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only at the parent: pass3.ac-guadeloupe.fr. dns0.ac-martinique.fr, mona.martinique.univ-ag.fr report NS dns0.ac-martinique.fr mona.martinique.univ-ag.fr.
    #7
  • ✓ Glue present and correct #8
    Glue is published for the nameservers inside the zone: dns0.ac-martinique.fr.
  • ✓ All names resolve #9
    Every nameserver name has an address and is not an alias.
  • ✓ Nameservers in different networks #10
    The nameservers are spread over 3 IPv4 /24s and 0 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS2199 (FR-DOM-MARTINIQUE - Renater, EU): 2 addresses; AS2471 (FR-DOM-GUADELOUPE - 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
  • !
    No IPv6
    None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.

  • ✗
    Lame delegation
    These nameservers don't answer authoritatively for the zone, so resolvers ignore them: pass3.ac-guadeloupe.fr (194.57.236.1): SERVFAIL, authoritative=false.

    #18
  • ✗
    No DNS over TCP
    DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: mona.martinique.univ-ag.fr (194.199.97.2): read tcp 46.225.38.91:43692->194.199.97.2:53: i/o timeout; pass3.ac-guadeloupe.fr (194.57.236.1): .
