info

.de country-code

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.

2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns.sml.de, pns.brv.net.

#6
✓ 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.
✓ Nameservers in different networks #10

The nameservers are spread over 2 IPv4 /24s and 0 IPv6 /48s.
i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS12923 (WIZARD-AS - Wizard Computersysteme GmbH, DE): 2 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.

#11
✓ Nameserver names under 2 TLDs #12

Nameserver names use the TLDs .de, .net.
!

No IPv6

None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.

Software version disclosed

These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns.sml.de: "9.16.50-Debian". Hide or replace the version string.

#17
✓ Zone transfers refused #18

No nameserver allows a zone transfer to the public.
✓ TCP supported #19

All nameservers answer over TCP.
✓ EDNS supported #20

All nameservers support EDNS(0).
✓ Public addresses #21

All nameserver addresses are publicly routable.

Unusual SOA timers

retry 1h should be shorter than refresh 1h; expire 1h is shorter than 7d; secondaries stop answering too soon when the primary is down; expire 1h must be longer than refresh + retry. Current values: refresh 1h, retry 1h, expire 1h, negative TTL 1d.

#23
✓ Primary is a public nameserver #24

The primary nameserver pns.brv.net is one of the listed nameservers.
✓ Contact service@wizard.de #25

The SOA RNAME service.wizard.de means service@wizard.de.
✓ Date-based serial #26

The serial 2026093001 follows the YYYYMMDDnn convention (2026-09-30).
