    2 nameservers
    Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns1.gnway.cn, ns1.gnway.com.
    #6
  • ✓ Parent and zone agree #7
    The parent delegation and the zone's NS records list the same nameservers.
  • !
    Glue differs from the zone
    The addresses at the parent (glue) differ from the addresses in the zone: ns1.gnway.com (glue 182.92.201.235, zone 120.24.111.15, 39.107.99.218, 39.107.225.151). 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 4 IPv4 /24s and 0 IPv6 /48s.
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS37963 (ALIBABA-CN-NET - Hangzhou Alibaba Advertising Co.,Ltd., CN): 6 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.
    #11
  • ✓ Nameserver names under 2 TLDs #12
    Nameserver names use the TLDs .cn, .com.
  • !
    No IPv6
    None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.

  • ✓ All respond #14
    All 6 nameserver addresses answered.
  • ✓ All authoritative #15
    Every responding nameserver answers authoritatively for the zone.
  • ✓ No recursion #16
    The nameservers do not answer recursive queries for other domains.
  • ✓ No version disclosed #17
    The nameservers don't reveal their software version.
  • ✓ Zone transfers refused #18
    No nameserver allows a zone transfer to the public.
  • ✗
    No DNS over TCP
    DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: ns1.gnway.cn (8.147.129.112): dial tcp 8.147.129.112:53: i/o timeout; ns1.gnway.cn (39.107.225.151): dial tcp 39.107.225.151:53: i/o timeout; ns1.gnway.cn (39.107.99.218): dial tcp 39.107.99.218:53: i/o timeout; ns1.gnway.com (120.24.111.15): dial tcp 120.24.111.15:53: i/o timeout; ns1.gnway.com (39.107.99.218): dial tcp 39.107.99.218:53: i/o timeout; ns1.gnway.com (39.107.225.151): dial tcp 39.107.225.151:53: i/o timeout.

    Very low TTLs
    These records have a TTL below 5m, causing extra queries and slower lookups: A (0s), NS (44s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 44s; resolvers may use either.

    No CAA records
    Without CAA records any certificate authority may issue certificates for this domain. A CAA record limits issuance to the CAs you use.
