    No DNS over TCP
    Nameservers · DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: ns1.vip.com (14.215.61.134): dial tcp 14.215.61.134:53: connect: connection refused; ns1.vipshop.com (14.215.61.134): dial tcp 14.215.61.134:53: connect: connection refused; ns7.vip.com (14.215.61.134): dial tcp 14.215.61.134:53: connect: connection refused; ns7.vipshop.com (14.215.61.134): dial tcp 14.215.61.134:53: connect: connection refused.

    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only at the parent: ns1.vipshop.com, ns11.vipshop.com, ns7.vipshop.com, ns8.vipshop.com. ns1.vip.com, ns1.vipshop.com, ns11.vipshop.com, ns7.vipshop.com, ns8.vip.com, ns8.vipshop.com report NS ns1.vip.com ns11.vip.com ns7.vip.com ns8.vip.com.

    No IPv6
    Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.

Problems

  • ✗
    No DMARC record
    DMARC · No DMARC record was found for this domain. DMARC is essential for preventing email spoofing. Add a DMARC record with p=reject or at least p=quarantine.
    #5
  • ✗
    No DKIM keys published
    DKIM · _domainkey.vip.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
  • !
    Hosts without IP addresses
    MX · The following MX hosts could not be resolved to IP addresses: mail.vip.com
    #10
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mail.vip.com
    #11
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    Not configured
    TLS · MTA-STS is not configured, so other mail servers fall back to unencrypted delivery when TLS fails or is stripped by an attacker. Publish a _mta-sts TXT record and a policy at https://mta-sts.<domain>/.well-known/mta-sts.txt.
