Checks

  • ✓ TTLs within range #32
    TTLs: A 1d, MX 1d, 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.
