    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 1.12.14.17, 1.12.14.18, 1.12.0.18, 18.134.75.163, 13.37.58.163, 162.62.49.74, 163.177.5.52, 1.12.0.17, 15.160.102.38, 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 13.48.202.4, 1.12.14.16, 1.12.0.16, 162.62.49.12, 1.12.0.19, 18.194.2.137, 1.12.14.19, 63.34.1.181, 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.
    #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 1d; resolvers may use either.
    #32

Problems

  • ✗
    No SPF record
    SPF · No SPF record was found for this domain. SPF is important for preventing email spoofing. Add an SPF record to specify which servers are authorized to send email for your domain.
    #6
  • ✗
    No DKIM keys published
    DKIM · _domainkey.search.bilibili.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
  • !
    No MX records
    MX · No MX records found. If this domain is used for email, add MX records to specify mail servers. If it never receives mail, publish a null MX ("MX 0 .").
    #9
  • !
    Subdomains unprotected (sp=none)
    DMARC · DMARC subdomain policy is sp=none, so spoofed mail from subdomains is not blocked. Consider sp=quarantine or sp=reject.
