Checks

• ✓ TTLs within range #32

  TTLs: A 10m, MX 10m, NS 10m. The NS TTL at the parent is 2d and in the zone 10m; 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.

  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.
