  • ✓ 7 nameservers #6
    Delegated to dns.grenoble-inp.fr, dns2.grenoble-inp.fr, eip1.u-ga.fr, eip2.u-ga.fr, nommay.univ-rouen.fr, ns-1.grenet.fr, ns-2.grenet.fr.
  • ✓ Parent and zone agree #7
    The parent delegation and the zone's NS records list the same nameservers.
  • ✓ 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 7 IPv4 /24s and 3 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS1942 (FR-TIGRE - Renater, EU): 5 addresses; AS2200 (FR-RENATER - Renater, FR): 6 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: dns.grenoble-inp.fr, dns2.grenoble-inp.fr, nommay.univ-rouen.fr.
