  • ✓ 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 0 IPv6 /48s.
  • ✓ 3 autonomous systems #11
    The nameservers are spread over: AS15456 (INTERNETX-AS - InterNetX GmbH, DE): 1 address; AS15790 (FINANZINFORMATIK-AS-OST - Finanz Informatik GmbH & Co. KG, DE): 2 addresses; AS9099 (FinanzInformatik-AS-Nord - Finanz Informatik GmbH & Co. KG, DE): 2 addresses.
  • ✓ Nameserver names under 3 TLDs #12
    Nameserver names use the TLDs .com, .de, .eu.
  • !
    No IPv6
    None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
