    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only in the zone: onera.onera.fr. doris.onecert.fr, esop.onera.fr, onera.onera.fr, osiris.onera.fr report NS doris.onecert.fr esop.onera.fr onera.onera.fr osiris.onera.fr.
    #7
  • ✓ Glue present and correct #8
    Glue is published for the nameservers inside the zone: esop.onera.fr, osiris.onera.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: AS1715 (FR-REMIP2000 - Renater, FR): 1 address; AS2426 (FR-RENATER-RUBIS - Renater, EU): 3 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
  • !
    No IPv6
    None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
