Checks

  • ✓ 3 nameservers #6
    Delegated to dns1.lis-lab.fr, dns2.lis-lab.fr, dns3.lis-lab.fr.
  • ✓ Parent and zone agree #7
    The parent delegation and the zone's NS records list the same nameservers.
  • ✓ Glue present and correct #8
    Glue is published for the nameservers inside the zone: dns1.lis-lab.fr, dns2.lis-lab.fr, dns3.lis-lab.fr.
  • ✓ 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 2 IPv6 /48s.
  • ✓ 3 autonomous systems #11
    The nameservers are spread over: AS16276 (OVH - OVH SAS, FR): 2 addresses; AS2200 (FR-RENATER - Renater, FR): 2 addresses; AS2457 (FR-RAIMU-2 - 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.
    #12
  • i
    Partly IPv6
    These nameservers have no IPv6 address: dns2.lis-lab.fr.
