Checks

  • ✓ 3 nameservers #6
    Delegated to ns2.etes.de, ns3.etes.de, tragedy.dante.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: tragedy.dante.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.
  • ✓ 3 autonomous systems #11
    The nameservers are spread over: AS12859 (NL-BIT - BIT BV, NL): 2 addresses; AS197540 (netcup-AS - netcup GmbH, DE): 2 addresses; AS9009 (M247 - M247 Europe SRL, RO): 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.
