Checks

    Delegated to nsx1.saint-gobain.com, nsx2.saint-gobain.com, nsx3.saint-gobain.com.
  • ✓ Parent and zone agree #7

    Glue is published for the nameservers inside the zone: nsx1.saint-gobain.com, nsx2.saint-gobain.com, nsx3.saint-gobain.com.
  • ✓ All names resolve #9

  • ✓ Nameservers in different networks #10
    The nameservers are spread over 3 IPv4 /24s and 3 IPv6 /48s.
  • ✓ 3 autonomous systems #11
    The nameservers are spread over: AS203926 (SGN-HK - Saint Gobain Group Digital & IT International SAS, FR): 2 addresses; AS209677 (SGT-US - Saint Gobain Group Digital & IT International SAS, FR): 2 addresses; AS49690 (SGT-FR - Saint Gobain Group Digital & IT International SAS, FR): 2 addresses.
  • i
    All nameserver names under .com
    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.
