The DS record at the parent matches a key in the zone: key tag 56410 (SHA256).

NSEC3 with extra iterations or salt

NSEC3 uses 1 iteration and a 16-byte salt. RFC 9276 recommends 0 iterations and no salt: extra iterations cost resolvers CPU and add no real protection, and some validators treat high counts as insecure.

Checks

✓ TTLs within range #32

TTLs: A 5m, MX 5m, NS 144m. The NS TTL at the parent is 1d and in the zone 144m; resolvers may use either.
✓ No CNAME at the apex #33

The zone apex has no CNAME record.

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.
