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.
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.

2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: dns1.domainname.de, dns2.domainname.de.

#6
✓ Parent and zone agree #7

The parent delegation and the zone's NS records list the same nameservers.
!

Glue differs from the zone

The addresses at the parent (glue) differ from the addresses in the zone: dns2.domainname.de (glue 94.130.69.251, zone 94.130.69.251, 2a01:4f8:10b:3350::2). Update the glue at your registrar.

#8
✓ 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 1 IPv6 /48.
i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS24940 (HETZNER-AS - Hetzner Online GmbH, DE): 3 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 .de

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
i

Partly IPv6

These nameservers have no IPv6 address: dns1.domainname.de.

✓ All respond #14

All 3 nameserver addresses answered.
✓ All authoritative #15

Every responding nameserver answers authoritatively for the zone.
✓ No recursion #16

The nameservers do not answer recursive queries for other domains.
!

Software version disclosed

These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: dns1.domainname.de: "PowerDNS Authoritative Server 5.0.8 (built Oct 7 2026 06:11:55 by root@localhost)"; dns2.domainname.de: "PowerDNS Authoritative Server 4.7.3". 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.

info

serial 2025100201 · primary ns1.info.at

✓ Serial 2025100201 everywhere #22

All nameservers serve the same version of the zone.
✓ Timers within recommendations #23

SOA refresh 3h, retry 1h, expire 7d, negative TTL 1d.
i

Hidden master

The primary nameserver ns1.info.at is not listed as a nameserver: a hidden master that only feeds the public secondaries. That is a common setup; make sure it is not reachable for zone transfers from outside.

#24
✓ Contact hostmaster@info.at #25

The SOA RNAME hostmaster.info.at means hostmaster@info.at.
✓ Date-based serial #26

The serial 2025100201 follows the YYYYMMDDnn convention (2025-10-02).
