  • ✓ 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): ns1.netbcp.com.
    #9
  • ✓ Nameservers in different networks #10
    The nameservers are spread over 10 IPv4 /24s and 6 IPv6 /48s.
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS12008 (VERCARA - Vercara, LLC, US): 20 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.
    #11
  • ✓ Nameserver names under 5 TLDs #12
    Nameserver names use the TLDs .com, .info, .net, .org, .uk.
  • ✓ All reachable over IPv6 #13
    Every nameserver has an IPv6 address.
