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

    #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

  • ✓ 3 nameservers #6
    Delegated to ns1.arxes.de, ns2.arxes.de, ns3.arxes.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 3 IPv4 /24s and 3 IPv6 /48s.
  • ✓ 4 autonomous systems #11
    The nameservers are spread over: AS15404 (UNSPECIFIED - COLT Technology Services Group Limited, GB): 1 address; AS198333 (DATAGROUP-AS - DATAGROUP SE, DE): 2 addresses; AS8220 (COLT - COLT Technology Services Group Limited, GB): 1 address; AS8422 (NETCOLOGNE - NetCologne Gesellschaft fur Telekommunikation mbH, DE): 2 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
  • ✓ All reachable over IPv6 #13
    Every nameserver has an IPv6 address.
