  • ✓ 3 nameservers #6
    Delegated to ns-open1.qq.com, ns-open2.qq.com, ns-open3.qq.com.
  • ✓ 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 16 IPv4 /24s and 2 IPv6 /48s.
  • ✓ 8 autonomous systems #11
    The nameservers are spread over: AS132203 (TENCENT-NET-AP-CN - Tencent Building, Kejizhongyi Avenue, CN): 12 addresses; AS135061 (UNICOM-ShenZhen-IDC - China Unicom Guangdong IP network, CN): 1 address; AS140979 (UNICOM-SHFT-IDC - China Unicom Shanghai FuTe IDC network, CN): 1 address; AS4134 (CHINANET-BACKBONE - No.31,Jin-rong Street, CN): 1 address; AS45090 (TENCENT-NET-AP - Shenzhen Tencent Computer Systems Company Limited, CN): 3 addresses; AS4811 (CHINANET-SHANGHAI-MAN - China Telecom (Group), CN): 3 addresses; 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 .com
    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
  • i
    Partly IPv6
    These nameservers have no IPv6 address: ns-open3.qq.com.
