    2 nameservers
    Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns1.ename.net, ns2.ename.net.
    #6
  • ✓ 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 5 IPv4 /24s and 2 IPv6 /48s.
  • ✓ 6 autonomous systems #11
    The nameservers are spread over: AS133775 (CHINATELECOM-Fujian-Xiamen-IDC1 - Xiamen, CN): 1 address; AS134763 (CT-DongGuan-IDC - CHINANET Guangdong province network, CN): 2 addresses; AS140227 (HKCICL-AS-AP - Hong Kong Communications International Co., Limited, HK): 1 address; AS4134 (CHINANET-BACKBONE - No.31,Jin-rong Street, CN): 1 address; AS4837 (CHINA169-Backbone - CHINA UNICOM China169 Backbone, CN): 1 address; AS9808 (CHINAMOBILE-CN - China Mobile Communications Group Co., Ltd., CN): 1 address.
  • i
    All nameserver names under .net
    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.
