    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only at the parent: ns3.paris-sorbonne.fr; only in the zone: ns0.paris-sorbonne.fr, ns0.sorbonne-universite.fr, ns1.sorbonne-universite.fr. ns1.paris-sorbonne.fr, ns1.sorbonne-universite.fr report NS ns0.paris-sorbonne.fr ns0.sorbonne-universite.fr ns1.paris-sorbonne.fr ns1.sorbonne-universite.fr ns2.paris-sorbonne.fr.
    #7
  • ✓ No glue needed #8
    All nameservers are outside the zone, so no glue records are needed.
  • ✓ 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: AS1307 (UNSPECIFIED - Renater, EU): 1 address; AS2200 (FR-RENATER - Renater, FR): 5 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.
