Problems

  • ✗
    CNAME at the apex
    Records · The zone apex is a CNAME to sh2.general.proxy.sogou.com. A CNAME can't coexist with the SOA and NS records (RFC 1034); use your provider's ALIAS/flattening feature instead.
    #33
  • !
    No IPv6
    Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13
  • !
    No EDNS
    Nameservers · These nameservers don't support EDNS(0), needed for DNSSEC and answers larger than 512 bytes: ns1.sogou.com (101.226.101.142), ns2.sogou.com (43.137.30.21).
    #20
  • !
    Unusual SOA timers
    SOA · refresh 5m is outside 20m–1d; negative caching TTL (minimum) 3m is outside 5m–1d (RFC 2308 recommends 1–3 hours). Current values: refresh 5m, retry 3m, expire 14d, negative TTL 3m.
    #23
  • !
    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

  • ✗
    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.soso.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 IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mxbiz1.qq.com, mxbiz2.qq.com
    #11
  • !
    Addresses without reverse DNS
    MX · These MX addresses have no PTR record, which many receivers treat as a spam signal: 103.86.78.3 (mxbiz1.qq.com), 103.86.78.2 (mxbiz1.qq.com), 43.154.252.202 (mxbiz2.qq.com), 43.154.252.16 (mxbiz2.qq.com). Ask your hosting provider to set one.
