    Glue differs from the zone
    The addresses at the parent (glue) differ from the addresses in the zone: dns-ch.xinnet.com (glue 162.14.25.230, 61.151.180.44, 61.240.129.103, zone 117.89.178.173, 1.12.0.4); dns-ch2.xinnet.com (glue 101.226.220.16, 129.211.176.224, 183.131.156.103, zone 1.12.0.1, 129.211.176.239). Update the glue at your registrar.
    #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 3 IPv4 /24s and 0 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS134756 (ChinaNet-NANJING-JISHAN-IDC - CHINANET Nanjing Jishan IDC network, CN): 1 address; AS45090 (TENCENT-NET-AP - Shenzhen Tencent Computer Systems Company Limited, CN): 3 addresses.
  • 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.
