2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns1.dns.com, ns2.dns.com.

#6
✓ Parent and zone agree #7

The parent delegation and the zone's NS records list the same nameservers.

Glue differs from the zone

The addresses at the parent (glue) differ from the addresses in the zone: ns1.dns.com (glue 154.23.191.128, 154.86.21.128, 2001:df2:f080:2::1:1, zone 154.86.21.128, 177.2.31.128, 2001:df2:f080:2::1:1); ns2.dns.com (glue 154.23.191.129, 154.86.21.129, 2001:df2:f080:2::1:2, zone 154.23.191.129, 177.2.31.129, 2001:df2:f080:2::1:2). Update the glue at your registrar.

#8
✓ All names resolve #9

Every nameserver name has an address and is not an alias.
i

One address family in one network

all IPv6 addresses are in 2001:df2:f080::/48, while the other address family is spread over several networks.

#10
i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS140227 (HKCICL-AS-AP - Hong Kong Communications International Co., Limited, HK): 6 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.

Nameservers not responding

✗

CNAME at the apex

The zone apex is a CNAME to lanzoui.com.a1.initba.com. A CNAME can't coexist with the SOA and NS records (RFC 1034); use your provider's ALIAS/flattening feature instead.

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.
