Checks

✓ TTLs within range #32

TTLs: A 4h, MX 4h, NS 1d. The NS TTL at the parent is 1h 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.

✓ CAA restricts issuance #35
