    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only at the parent: ns4.oniris-nantes.fr, ns5.oniris-nantes.fr. ns1.oniris-nantes.fr report NS ns1.oniris-nantes.fr ns2.oniris-nantes.fr ns3.oniris-nantes.fr.

    Glue is published for the nameservers inside the zone: ns1.oniris-nantes.fr, ns2.oniris-nantes.fr, ns3.oniris-nantes.fr, ns4.oniris-nantes.fr, ns5.oniris-nantes.fr.
  • ✗
    Nameserver names don't resolve
    These nameservers have no A or AAAA record, so they can't be reached (lame delegation): ns4.oniris-nantes.fr, ns5.oniris-nantes.fr.
    #9
  • ✓ Nameservers in different networks #10
    The nameservers are spread over 2 IPv4 /24s and 0 IPv6 /48s.
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS2200 (FR-RENATER - Renater, FR): 3 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.
    #11
  • 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.oniris-nantes.fr, ns2.oniris-nantes.fr, ns3.oniris-nantes.fr.
