  • ✓ 7 nameservers #6
    Delegated to ns1.qunar.com, ns3.qunar.com, ns4.qunar.com, ns5.qunar.com, ns6.qunar.com, ns8.qunar.com, ns9.qunar.com.
  • ✓ Parent and zone agree #7
    The parent delegation and the zone's NS records list the same nameservers.
  • ✓ Glue present and correct #8
    Glue is published for the nameservers inside the zone: ns1.qunar.com, ns3.qunar.com, ns4.qunar.com, ns5.qunar.com, ns6.qunar.com, ns8.qunar.com, ns9.qunar.com.
  • ✓ All names resolve #9
    Every nameserver name has an address and is not an alias.
  • i
    One address family in one network
    all IPv6 addresses are in 2403:a200:a200::/48, while the other address family is spread over several networks.
    #10
  • ✓ 3 autonomous systems #11
    The nameservers are spread over: AS17428 (CHINA-ABITCOOL - 21Vianet.Co.,Ltd, CN): 3 addresses; AS23724 (CHINANET-IDC-BJ-AP - IDC, China Telecommunications Corporation, CN): 5 addresses; AS9308 (CHINA-ABITCOOL - Abitcool(China) Inc., 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
  • i
    Partly IPv6
    These nameservers have no IPv6 address: ns5.qunar.com, ns6.qunar.com, ns8.qunar.com, ns9.qunar.com.

    Nameservers not responding
    These addresses did not answer, so resolvers waste time on timeouts: ns1.qunar.com (2403:a200:a200:1d00::e): read udp [2a01:4f8:1c1c:eebf::1]:33006->[2403:a200:a200:1d00::e]:53: i/o timeout.

    The nameservers do not answer recursive queries for other domains.

    Software version disclosed
    These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.qunar.com: "0.0.0"; ns3.qunar.com: "0.0.0"; ns4.qunar.com: "0.0.0"; ns5.qunar.com: "0.0.0"; ns6.qunar.com: "0.0.0"; ns8.qunar.com: "0.0.0"; ns9.qunar.com: "0.0.0".

  • ✓ Zone transfers refused #18
    No nameserver allows a zone transfer to the public.

    Very low TTLs
    These records have a TTL below 5m, causing extra queries and slower lookups: A (1m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 10m; resolvers may use either.
