  • i
    .de is a country-code TLD (ccTLD)

  • ✓ 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.

  • ✓ 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 8 IPv4 /24s and 7 IPv6 /48s.
  • ✓ 4 autonomous systems #11
    The nameservers are spread over: AS133466 (BOSCH-NET-AP - Robert Bosch GmbH, SG): 3 addresses; AS20940 (AKAMAI-ASN1 - Akamai International B.V., NL): 1 address; AS21342 (AKAMAI-ASN2 - Akamai International B.V., NL): 10 addresses; AS9183 (UNSPECIFIED - Robert Bosch Gesellschaft mit Beschraenkter Haftung, DE): 3 addresses.
  • 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: ns6.fe.bosch.de.
