    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only in the zone: ns14.dnsmadeeasy.com, ns15.dnsmadeeasy.com. ns10.dnsmadeeasy.com, ns11.dnsmadeeasy.com, ns12.dnsmadeeasy.com, ns13.dnsmadeeasy.com, ns14.dnsmadeeasy.com, ns15.dnsmadeeasy.com report NS ns10.dnsmadeeasy.com ns11.dnsmadeeasy.com ns12.dnsmadeeasy.com ns13.dnsmadeeasy.com ns14.dnsmadeeasy.com ns15.dnsmadeeasy.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 6 IPv4 /24s and 6 IPv6 /48s.
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS16552 (DIGICERT - Tiggee LLC, US): 12 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.
    #11
  • 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
  • ✓ All reachable over IPv6 #13
    Every nameserver has an IPv6 address.

    Hidden master
    The primary nameserver ns20.digicertdns.com is not listed as a nameserver: a hidden master that only feeds the public secondaries. That is a common setup; make sure it is not reachable for zone transfers from outside.

Checks

  • ✓ TTLs within range #32
    TTLs: A 5m, MX 1h, NS 1d. The NS TTL at the parent is 2d and in the zone 1d; resolvers may use either.
  • ✓ No CNAME at the apex #33
    The zone apex has no CNAME record.
  • i
    Wildcard record
    A random name under the zone resolves, so there is a wildcard (*) record. Typos and non-existent hosts resolve too, which can confuse mail and certificate checks.
    #34
  • i
    No CAA records
    Without CAA records any certificate authority may issue certificates for this domain. A CAA record limits issuance to the CAs you use.
