  • ✓ 6 nameservers #6
    Delegated to pch1.salesforce-dns.com, pch2.salesforce-dns.com, udns1.salesforce.com, udns2.salesforce.com, udns3.salesforce.com, udns4.salesforce.com.
  • ✓ 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: udns1.salesforce.com, udns2.salesforce.com, udns3.salesforce.com, udns4.salesforce.com.
  • ✓ 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 6 IPv4 /24s and 6 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS12008 (VERCARA - Vercara, LLC, US): 8 addresses; AS42 (WOODYNET-1 - WoodyNet, Inc., US): 4 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.
