    #8
  • ✓ 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 8 IPv4 /24s and 0 IPv6 /48s.
  • ✓ 4 autonomous systems #11
    The nameservers are spread over: AS137718 (VOLCANO-ENGINE - Beijing Volcano Engine Technology Co., Ltd., CN): 1 address; AS16509 (AMAZON-02 - Amazon.com, Inc., US): 4 addresses; AS37963 (ALIBABA-CN-NET - Hangzhou Alibaba Advertising Co.,Ltd., CN): 5 addresses; AS4811 (CHINANET-SHANGHAI-MAN - China Telecom (Group), 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
  • !
    No IPv6
    None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
