    Glue differs from the zone
    The addresses at the parent (glue) differ from the addresses in the zone: limdns.unilim.fr (glue 164.81.1.4, zone 164.81.1.4, 2001:660:6201:1::4); limdns2.unilim.fr (glue 164.81.1.5, zone 164.81.1.5, 2001:660:6201:1::5). Update the glue at your registrar.
    #8
  • ✓ 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 2 IPv4 /24s and 2 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS1935 (FR-RENATER-LIMOUSIN - Renater, EU): 2 addresses; AS2200 (FR-RENATER - Renater, FR): 4 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
  • ✓ All reachable over IPv6 #13
    Every nameserver has an IPv6 address.
