  • ✓ No glue needed #8
    All nameservers are outside the zone, so no glue records are needed.

    Nameserver names don't resolve
    These nameservers have no A or AAAA record, so they can't be reached (lame delegation): fwd02dmzadc01.rsm02dmz.net, fwd02dmzadc02.rsm02dmz.net, fwd02dmzdns03.rsm02dmz.net, fwd02dmzdns04.rsm02dmz.net.

  • ✓ Nameservers in different networks #10
    The nameservers are spread over 2 IPv4 /24s and 2 IPv6 /48s.
  • ✓ 3 autonomous systems #11
    The nameservers are spread over: AS19149 (US-SIGNAL-IA01 - US Signal Company, L.L.C., US): 1 address; AS54519 (US-SIGNAL-WI02 - US Signal Company, L.L.C., US): 10 addresses; AS6939 (HURRICANE - Hurricane Electric LLC, US): 2 addresses.

    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.
