Very low TTLs

These records have a TTL below 5m, causing extra queries and slower lookups: A (1m), AAAA (1m), MX (1m), NS (1m40s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 1m40s; resolvers may use either.

#32
✓ 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.
