    Very low TTLs
    These records have a TTL below 5m, causing extra queries and slower lookups: A (3m), MX (3m), NS (3m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1d and in the zone 3m; resolvers may use either.

  • ✓ No CNAME at the apex #33
    The zone apex has no CNAME record.
  • ✓ No wildcard #34
    Names that don't exist return NXDOMAIN.

    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.
