  • ✗
    Nameservers not responding
    Nameservers · These addresses did not answer, so resolvers waste time on timeouts: ns4.xunlei.net (47.103.34.114): read udp 46.225.38.91:60108->47.103.34.114:53: i/o timeout.

  • ✗
    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.xunlei.net (47.106.189.11): dial tcp 47.106.189.11:53: i/o timeout; ns1.xunlei.net (2408:4003:1100:9702:ef17:664d:701e:47b): dial tcp [2408:4003:1100:9702:ef17:664d:701e:47b]:53: i/o timeout; ns2.xunlei.net (39.104.185.30): dial tcp 39.104.185.30:53: i/o timeout; ns2.xunlei.net (2408:4004:100:2e06:5c66:3a14:1677:c50d): dial tcp [2408:4004:100:2e06:5c66:3a14:1677:c50d]:53: i/o timeout; ns3.xunlei.net (110.41.172.39): dial tcp 110.41.172.39:53: i/o timeout; ns3.xunlei.net (2407:c080:10:13d1:2340:876c:8130:41f7): dial tcp [2407:c080:10:13d1:2340:876c:8130:41f7]:53: i/o timeout; ns4.xunlei.net (2408:4002:10c4:1f00:c015:8df:4e9c:1565): dial tcp [2408:4002:10c4:1f00:c015:8df:4e9c:1565]:53: i/o timeout; ns5.xunlei.net (39.98.182.239): dial tcp 39.98.182.239:53: i/o timeout; ns5.xunlei.net (2408:4001:20b:9600:e630:979:a6f:66b5): dial tcp [2408:4001:20b:9600:e630:979:a6f:66b5]:53: i/o timeout.

  • !
    Invalid contact address
    SOA · The SOA RNAME "root.localhost" is not a valid mailbox (expected e.g. hostmaster.example.com).
    #25
  • !
    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.
    #27
  • !
    Very low TTLs
    Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (1m), AAAA (1m), MX (1m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 30m; resolvers may use either.

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
  • !
    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: mx1.xunlei.com, mx2.xunlei.com, mx3.xunlei.com
    #11
  • !
    Hosts are CNAMEs
    MX · MX records must point to a host name with A/AAAA records, not to a CNAME: mx1.xunlei.com -> mx1.qiye.aliyun.com, mx2.xunlei.com -> mx2.qiye.aliyun.com, mx3.xunlei.com -> mx3.qiye.aliyun.com
    #22
  • !
    Addresses without reverse DNS
    MX · These MX addresses have no PTR record, which many receivers treat as a spam signal: 47.246.167.188 (mx1.xunlei.com), 47.246.137.47 (mx3.xunlei.com). Ask your hosting provider to set one.
    #30
  • !
    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.
