    Glue differs from the zone

    #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 6 IPv4 /24s and 0 IPv6 /48s.
  • ✓ 5 autonomous systems #11
    The nameservers are spread over: AS14618 (AMAZON-AES - Amazon.com, Inc., US): 1 address; AS16509 (AMAZON-02 - Amazon.com, Inc., US): 1 address; AS37963 (ALIBABA-CN-NET - Hangzhou Alibaba Advertising Co.,Ltd., CN): 1 address; AS45062 (Netease-Network - NetEase Building No.16 Ke Yun Road,, CN): 2 addresses; AS55990 (HWCSNET - Huawei Cloud Service data center, CN): 1 address.
  • 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.

    Wildcard record
    A random name under the zone resolves, so there is a wildcard (*) record. Typos and non-existent hosts resolve too, which can confuse mail and certificate checks.

    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.
