Checks

  • ✓ TTLs within range #32
    TTLs: A 1h, AAAA 1h, MX 5m, NS 1d. The NS TTL at the parent is 2d 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.
    #34
  • ✓ CAA restricts issuance #35
    Certificates may be issued by: letsencrypt.org, sectigo.com, godaddy.com, starfieldtech.com, comodoca.com, trust-provider.com, usertrust.com, digicert.com, amazon.com.
