Checks

  • i
    .de is a country-code TLD (ccTLD)
    Country-code TLD: governed by its local registry under national policy, not by an ICANN contract. Registrar accreditation, dispute resolution and RDAP/WHOIS rules are set by the registry.
    #1
  • ✓ TLD delegated and signed #2
    .de is delegated in the root zone and DNSSEC-signed.
  • i
    Registration data not available
    No registration data via RDAP: the registry of .de offers no RDAP service. Many ccTLD registries don't offer RDAP; check the registry's WHOIS instead.

    Signed but not delegated securely
    The zone is signed but the parent has no DS record, so the signatures are not used. Publish the DS record at your registrar.

    Key algorithms: RSASHA256 (8).

    The earliest DNSKEY/SOA signature expires at 2026-10-29 00:00 UTC.
  • !
    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.
  • 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
  • i
    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.
