    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only at the parent: newwww.lri.fr, ns2.nic.fr. ext.lri.fr, ns2.nic.fr report NS ext.lri.fr.
    #7
  • ✓ Glue present and correct #8
    Glue is published for the nameservers inside the zone: ext.lri.fr, newwww.lri.fr.
  • ✗
    Nameserver names don't resolve
    These nameservers have no A or AAAA record, so they can't be reached (lame delegation): newwww.lri.fr.
    #9
  • ✓ Nameservers in different networks #10
    The nameservers are spread over 2 IPv4 /24s and 1 IPv6 /48.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS2269 (FR-U-PARISSUD-ORSAY - Renater, EU): 1 address; AS2486 (NIC-FR-DNS-UNICAST-PARIS2 - AFNIC (Association Francaise pour le Nommage Internet en Cooperation), FR): 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: ext.lri.fr.
