Problems

  • !
    TLD not DNSSEC-signed
    Registration · The root has no DS record for .nl, so DNSSEC for domains under it can't be validated.
    #2
  • !
    Signed, not validated by the resolver
    DNSSEC · The zone is signed and has a DS record, but the resolver did not mark the answer as validated. The resolver may not validate, or the TLD is not signed.
    #27
  • !
    Very low TTLs
    Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (1m). Low TTLs are useful just before a planned change.
