    Nameserver names don't resolve
    These nameservers have no A or AAAA record, so they can't be reached (lame delegation): lagaffe.univ-angers.fr.
    #9
  • ✓ Nameservers in different networks #10
    The nameservers are spread over 3 IPv4 /24s and 0 IPv6 /48s.

    The nameservers are spread over: AS2200 (FR-RENATER - Renater, FR): 2 addresses; AS2462 (FR-U-ANGERS - Renater, EU): 1 address.
  • 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.
