  • 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

Checks

  • ✓ 3 nameservers #6
    Delegated to conic.openstreetmap.de, goode.openstreetmap.de, robinson.openstreetmap.de.
  • ✓ Parent and zone agree #7
    The parent delegation and the zone's NS records list the same nameservers.
  • ✓ Glue present and correct #8
    Glue is published for the nameservers inside the zone: conic.openstreetmap.de, goode.openstreetmap.de, robinson.openstreetmap.de.
  • ✓ 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.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS24940 (HETZNER-AS - Hetzner Online GmbH, DE): 4 addresses; AS29691 (NINE - Nine Internet Solutions AG, CH): 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.
