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.

Checks

  • ✓ 4 nameservers #6
    Delegated to ns1.max-it.de, ns2.max-it.de, ns3.max-it.de, ns4.max-it.de.
  • ✓ 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 4 IPv4 /24s and 0 IPv6 /48s.
  • ✓ 3 autonomous systems #11
    The nameservers are spread over: AS24764 (MAX-IT-AS - m.a.x. Informationstechnologie AG, DE): 2 addresses; AS24940 (HETZNER-AS - Hetzner Online GmbH, DE): 1 address; AS6878 (AS6878 - T-Systems International GmbH, DE): 1 address.
  • 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
  • !
    No IPv6
    None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13

    Software version disclosed
    These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.max-it.de: "PowerDNS Authoritative Server 4.9.17 (built Aug 5 2026 13:26:37 by root@localhost)"; ns2.max-it.de: "PowerDNS Authoritative Server 4.9.17 (built Aug 5 2026 13:26:37 by root@localhost)"; ns3.max-it.de: "PowerDNS Authoritative Server 4.9.17 (built Aug 5 2026 13:26:37 by root@localhost)"; ns4.max-it.de: "PowerDNS Authoritative Server 4.9.17 (built Aug 5 2026 13:26:37 by root@localhost)". Hide or replace the version string.
