  • ✓ 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 4 IPv4 /24s and 3 IPv6 /48s.
  • ✓ 3 autonomous systems #11
    The nameservers are spread over: AS2200 (FR-RENATER - Renater, FR): 4 addresses; AS2202 (FR-RENATER-REAUMUR - Renater, EU): 2 addresses; 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
  • ✓ All reachable over IPv6 #13
    Every nameserver has an IPv6 address.
