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.

  • !
    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only at the parent: dns1.noris.net, dns2.noris.net, dns3.noris.net, ns.slmedien.de; only in the zone: dns.buschglatz.net, dns.noris.ch, dns.noris.de, dns.noris.net. dns.buschglatz.net, dns.noris.ch, dns.noris.de, dns.noris.net, dns1.noris.net, dns2.noris.net, dns3.noris.net, ns.slmedien.de report NS dns.buschglatz.net dns.noris.ch dns.noris.de dns.noris.net.
    #7
  • ✓ 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 3 IPv6 /48s.
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS12337 (NORIS-NETWORK - noris network AG, DE): 11 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.
  • i
    Partly IPv6
    These nameservers have no IPv6 address: dns.buschglatz.net, dns1.noris.net, dns2.noris.net, dns3.noris.net, ns.slmedien.de.
