  • ✓ 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 6 IPv4 /24s and 0 IPv6 /48s.
  • ✓ 6 autonomous systems #11
    The nameservers are spread over: AS141679 (CHINATELECOM-IDC-BTHBD-AP - China Telecom Beijing Tianjin Hebei Big Data Industry Park Branch, CN): 1 address; AS4134 (CHINANET-BACKBONE - No.31,Jin-rong Street, CN): 1 address; AS4808 (CHINA169-BJ - China Unicom Beijing Province Network, CN): 1 address; AS4811 (CHINANET-SHANGHAI-MAN - China Telecom (Group), CN): 1 address; AS4837 (CHINA169-Backbone - CHINA UNICOM China169 Backbone, CN): 1 address; AS55992 (QIHOO - Beijing Qihu Technology Company Limited, 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.
