    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only at the parent: ns3.ixsystems.com. ns1.ixsystems.com, ns2.ixsystems.com, ns3.ixsystems.com report NS ns1.ixsystems.com ns2.ixsystems.com.
    #7
  • ✓ 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 3 IPv4 /24s and 0 IPv6 /48s.
  • ✓ 3 autonomous systems #11
    The nameservers are spread over: AS14061 (DIGITALOCEAN-ASN - DigitalOcean, LLC, US): 1 address; AS18934 (TENHATS - TenHats, LLC, US): 1 address; AS7018 (ATT-INTERNET4 - AT&T Enterprises, LLC, US): 1 address.
  • 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.
