    2 nameservers
    Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: s1.dnsns5.com, s2.dnsns5.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 11 IPv4 /24s and 7 IPv6 /48s.
  • ✓ 9 autonomous systems #11
    The nameservers are spread over: AS134768 (CHINANET-SHAANXI-CLOUD-BASE - CHINANET SHAANXI province Cloud Base network, CN): 2 addresses; AS139201 (CHINANET-Jiangxi-Jiujiang-IDC - Jiangxi Jiujiang IDC, CN): 1 address; AS146817 (FXNET - Hubei Feixun Network Co., Ltd, CN): 1 address; AS23724 (CHINANET-IDC-BJ-AP - IDC, China Telecommunications Corporation, CN): 1 address; AS4134 (CHINANET-BACKBONE - No.31,Jin-rong Street, CN): 2 addresses; AS4837 (CHINA169-Backbone - CHINA UNICOM China169 Backbone, CN): 6 addresses; AS58466 (CT-Guangzhou-IDC - CHINANET Guangdong province network, CN): 1 address; AS63023 (AS-GLOBALTELEHOST - GTHost, US): 2 addresses; 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.
