2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: damao.ns.giantpanda.com, yangguang.ns.giantpanda.com.

#6
✓ 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 0 IPv6 /48s.
i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS16509 (AMAZON-02 - Amazon.com, Inc., US): 2 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
!

No IPv6

None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.

All 2 nameserver addresses answered.
✓ All authoritative #15

Every responding nameserver answers authoritatively for the zone.
✗

Open recursion

These nameservers resolve names for anyone, which makes them usable for DNS amplification attacks and cache poisoning: damao.ns.giantpanda.com (3.33.232.36), yangguang.ns.giantpanda.com (75.2.45.63). Disable recursion on authoritative servers.

#16
✓ No version disclosed #17

The nameservers don't reveal their software version.
✓ Zone transfers refused #18

No nameserver allows a zone transfer to the public.
✓ TCP supported #19

All nameservers answer over TCP.
!

No EDNS

These nameservers don't support EDNS(0), needed for DNSSEC and answers larger than 512 bytes: damao.ns.giantpanda.com (3.33.232.36), yangguang.ns.giantpanda.com (75.2.45.63).

#20
✓ Public addresses #21

All nameserver addresses are publicly routable.

✓ TTLs within range #32

TTLs: A 10m, AAAA 10m, MX 10m, NS 10m. The NS TTL at the parent is 2d and in the zone 10m; 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.
