  • ✗
    Nameservers not responding
    Nameservers · These addresses did not answer, so resolvers waste time on timeouts: dns2.youku.com (106.11.35.17): read udp 46.225.38.91:46855->106.11.35.17:53: i/o timeout; dns3.youku.com (2401:b180:4100::9): read udp [2a01:4f8:1c1c:eebf::1]:57518->[2401:b180:4100::9]:53: i/o timeout.

    Unusual SOA timers
    SOA · expire 1h is shorter than 7d; secondaries stop answering too soon when the primary is down; expire 1h must be longer than refresh + retry. Current values: refresh 1h, retry 20m, expire 1h, negative TTL 6m.

    Not signed
    DNSSEC · The zone is not signed with DNSSEC, so answers can be spoofed. Enable DNSSEC at your DNS provider and publish the DS record at your registrar.

Problems

  • ✗
    Policy: none (monitoring only)
    DMARC · DMARC policy is set to 'none', which only monitors but doesn't protect against spoofing. Consider upgrading to 'quarantine' or ideally 'reject'.
    #4
  • ✗
    No SPF record
    SPF · No SPF record was found for this domain. SPF is important for preventing email spoofing. Add an SPF record to specify which servers are authorized to send email for your domain.
    #6
  • ✗
    No DKIM keys published
    DKIM · _domainkey.v.youku.com does not exist (NXDOMAIN), so no DKIM keys are published. DKIM helps prevent email spoofing. Configure DKIM with your email service provider.
    #7
  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    No MX records
    MX · No MX records found. If this domain is used for email, add MX records to specify mail servers. If it never receives mail, publish a null MX ("MX 0 .").
    #9
  • !
    Report address not authorized
    DMARC · These report addresses are in another domain that has not agreed to receive your reports, so receivers will not send them: mailto:dmarc_alibaba@service.alibaba.com (needs youku.com._report._dmarc.service.alibaba.com). Ask the report provider to publish the record, or check the address.
