    Glue differs from the zone
    Delegation · The addresses at the parent (glue) differ from the addresses in the zone: ns3.dnsv5.com (glue 1.12.0.17, 1.12.0.18, 1.12.14.17, 1.12.14.18, 101.227.168.52, 108.136.87.44, 163.177.5.52, 220.196.136.52, 2402:4e00:1470:2::f, 35.165.107.227, zone 18.134.75.163, 162.62.49.74, 1.12.14.18, 13.37.58.163, 1.12.14.17, 1.12.0.17, 163.177.5.52, 15.160.102.38, 1.12.0.18, 240d:c000:3011::10); ns4.dnsv5.com (glue 1.12.0.16, 1.12.0.19, 1.12.14.16, 1.12.14.19, 117.135.128.152, 124.64.205.152, 13.37.58.163, 2402:4e00:111:fff::8, 49.7.107.152, zone 1.12.0.19, 1.12.0.16, 1.12.14.16, 162.62.49.12, 18.194.2.137, 63.34.1.181, 1.12.14.19, 13.48.202.4, 240d:c000:3011::f). Update the glue at your registrar.

    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns3.dnsv5.com: "DNSPod AUTHORITY DNS 7.3.2512.01"; ns4.dnsv5.com: "DNSPod AUTHORITY DNS 7.3.2512.01". Hide or replace the version string.

    Unusual SOA timers
    SOA · negative caching TTL (minimum) 3m is outside 5m–1d (RFC 2308 recommends 1–3 hours). Current values: refresh 1h, 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

  • ✗
    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
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    No aggregate reports (rua)
    DMARC · DMARC record has no rua tag, so you receive no aggregate reports about who sends mail as your domain. Add rua=mailto:...
    #19
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: selector1 (1024 bits), selector2 (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.
