  • ✓ 6 nameservers #6
    Delegated to ns1.363.hk, ns2.363.hk, ns3.363.hk, ns4.363.hk, ns5.363.hk, ns6.363.hk.
  • ✓ 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.
  • i
    One address family in one network
    all IPv6 addresses are in 240e:d9:c200::/48, while the other address family is spread over several networks.
    #10
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS38283 (CHINANET-SCIDC-AS-AP - CHINANET SiChuan Telecom Internet Data Center, CN): 16 addresses; AS4811 (CHINANET-SHANGHAI-MAN - China Telecom (Group), CN): 3 addresses.
  • i
    All nameserver names under .hk
    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.
