    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only at the parent: dns0.ac-martinique.fr. pass-ren.ac-limoges.fr, pass3.ac-guadeloupe.fr report NS pass-ren.ac-limoges.fr pass3.ac-guadeloupe.fr.

  • ✓ Glue present and correct #8
    Glue is published for the nameservers inside the zone: pass3.ac-guadeloupe.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.
  • ✓ 3 autonomous systems #11
    The nameservers are spread over: AS2199 (FR-DOM-MARTINIQUE - Renater, EU): 1 address; AS2200 (FR-RENATER - Renater, FR): 1 address; 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.

  • ✓ Zone transfers refused #18
    No nameserver allows a zone transfer to the public.
  • ✗
    No DNS over TCP

    Very low TTLs
    These records have a TTL below 5m, causing extra queries and slower lookups: A (3m), NS (3m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 3m; resolvers may use either.
