    2 nameservers
    Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns3.dnsv4.com, ns4.dnsv4.com.
    #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 13 IPv4 /24s and 2 IPv6 /48s.
  • ✓ 10 autonomous systems #11
    The nameservers are spread over: AS132203 (TENCENT-NET-AP-CN - Tencent Building, Kejizhongyi Avenue, CN): 4 addresses; AS136958 (UNICOM-GuangZhou-IDC - China Unicom Guangdong IP network, CN): 1 address; AS17621 (CNCGROUP-SH - China Unicom Shanghai network, CN): 1 address; AS23724 (CHINANET-IDC-BJ-AP - IDC, China Telecommunications Corporation, 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): 5 addresses; AS4808 (CHINA169-BJ - China Unicom Beijing Province Network, CN): 1 address; AS4811 (CHINANET-SHANGHAI-MAN - China Telecom (Group), CN): 1 address; AS56046 (CMNET-Jiangsu-AP - China Mobile communications corporation, CN): 1 address; AS9808 (CHINAMOBILE-CN - China Mobile Communications Group Co., Ltd., CN): 2 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
  • ✓ All reachable over IPv6 #13
    Every nameserver has an IPv6 address.
