TLD: .de (country-code)
ICANN policies apply: no

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.

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.

✓ 4 nameservers #6

Delegated to ns-cloud-b1.googledomains.com, ns-cloud-b2.googledomains.com, ns-cloud-b3.googledomains.com, ns-cloud-b4.googledomains.com.
✓ Parent and zone agree #7

The parent delegation and the zone's NS records list the same nameservers.
✓ No glue needed #8

All nameservers are outside the zone, so no glue records are needed.
✓ All names resolve #9

Every nameserver name has an address and is not an alias.

One address family in one network

all IPv6 addresses are in 2001:4860:4802::/48, while the other address family is spread over several networks.

#10
i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS15169 (GOOGLE - Google LLC, US): 8 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.

#11
i

All nameserver names under .com

All nameserver names are under one TLD, so a problem with that TLD also makes the nameservers unreachable. Some operators use names under two TLDs for extra resilience.

#12
✓ All reachable over IPv6 #13

Every nameserver has an IPv6 address.

✓ Primary is a public nameserver #24

The primary nameserver ns-cloud-b1.googledomains.com is one of the listed nameservers.
✓ Contact cloud-dns-hostmaster@google.com #25

The SOA RNAME cloud-dns-hostmaster.google.com means cloud-dns-hostmaster@google.com.

NSEC3 with extra iterations or salt

NSEC3 uses 1 iteration and a 8-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.

✓ TTLs within range #32

TTLs: A 3h, MX 3h, NS 6h. The NS TTL at the parent is 1d and in the zone 6h; resolvers may use either.
✓ No CNAME at the apex #33

The zone apex has no CNAME record.

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.
