  • ✓ 4 nameservers #6
    Delegated to ns1.iqvia.com, ns2.iqvia.com, ns3.iqvia.com, ns4.iqvia.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: ns1.iqvia.com, ns2.iqvia.com, ns3.iqvia.com, ns4.iqvia.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 2 IPv4 /24s and 0 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS215429 (Ireland - IQVIA SOLUTIONS HQ LTD, GB): 2 addresses; AS394138 (IQVIA-DURHAM-6A - IQVIA Holdings Inc, US): 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
  • !
    No IPv6
    None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
