    CNAME at the apex
    The zone apex is a CNAME to urldance-com-idvrq8v.qiniudns.com. A CNAME can't coexist with the SOA and NS records (RFC 1034); use your provider's ALIAS/flattening feature instead.

    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.
    #34
  • i
    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.
