    Nameservers not responding
    Nameservers · These addresses did not answer, so resolvers waste time on timeouts: ns1.qunar.com (2403:a200:a200:1d00::e): read udp [2a01:4f8:1c1c:eebf::1]:33006->[2403:a200:a200:1d00::e]: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.qunar.com (59.151.61.59): dial tcp 59.151.61.59:53: i/o timeout; ns3.qunar.com (59.151.51.77): dial tcp 59.151.51.77:53: i/o timeout; ns3.qunar.com (2403:a200:a200:1d00::f): dial tcp [2403:a200:a200:1d00::f]:53: connect: no route to host; ns4.qunar.com (59.151.51.78): dial tcp 59.151.51.78:53: i/o timeout; ns4.qunar.com (2403:a200:a200:1d00::10): dial tcp [2403:a200:a200:1d00::10]:53: connect: no route to host; ns5.qunar.com (120.132.34.98): dial tcp 120.132.34.98:53: i/o timeout; ns6.qunar.com (120.132.34.99): dial tcp 120.132.34.99:53: i/o timeout; ns8.qunar.com (211.151.112.14): dial tcp 211.151.112.14:53: i/o timeout; ns9.qunar.com (211.151.112.15): dial tcp 211.151.112.15:53: i/o timeout.

    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.qunar.com: "0.0.0"; ns3.qunar.com: "0.0.0"; ns4.qunar.com: "0.0.0"; ns5.qunar.com: "0.0.0"; ns6.qunar.com: "0.0.0"; ns8.qunar.com: "0.0.0"; ns9.qunar.com: "0.0.0". Hide or replace the version string.

    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). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 10m; resolvers may use either.

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
  • !
    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: mailvip1.qunar.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
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: default (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    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.
