• ✓ 4 nameservers #6

  Delegated to ns1gmz.name.com, ns2fgv.name.com, ns3hjx.name.com, ns4kpx.name.com.
• ✓ Parent and zone agree #7

  The parent delegation and the zone's NS records list the same nameservers.
• ✓ 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 2 IPv4 /24s and 2 IPv6 /48s.
• i

  All nameservers in one AS

  All nameserver addresses are announced by one network operator (AS62597 (NSONE - NSONE 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
• 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.

8 of 8 addresses answer authoritatively

• ✓ All authoritative #15

• ✓ No recursion #16

  The nameservers do not answer recursive queries for other domains.

  Hidden master

  The primary nameserver ns1.name.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.

• ✓ Contact hostmaster@nsone.net #25

  The SOA RNAME hostmaster.nsone.net means hostmaster@nsone.net.

Checks

• ✓ TTLs within range #32

  TTLs: A 5m, MX 1h, NS 5m. The NS TTL at the parent is 2d and in the zone 5m; 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.

  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.
