    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only at the parent: ns1.myir.com, ns2.myir.com. ns-1515.awsdns-61.org, ns-1589.awsdns-06.co.uk, ns-300.awsdns-37.com, ns-837.awsdns-40.net report NS ns-1515.awsdns-61.org ns-1589.awsdns-06.co.uk ns-300.awsdns-37.com ns-837.awsdns-40.net.
    #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 6 IPv4 /24s and 4 IPv6 /48s.
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS16509 (AMAZON-02 - Amazon.com, Inc., US): 8 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 4 TLDs #12
    Nameserver names use the TLDs .com, .net, .org, .uk.
  • i
    Partly IPv6
    These nameservers have no IPv6 address: ns1.myir.com, ns2.myir.com.
