Problems

  • ✗
    CNAME at the apex
    Records · The zone apex is a CNAME to ip138.com.lxdns.com. A CNAME can't coexist with the SOA and NS records (RFC 1034); use your provider's ALIAS/flattening feature instead.
    #33
  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns3.dnsv4.com: "DNSPod AUTHORITY DNS 7.3.2512.01"; ns4.dnsv4.com: "DNSPod AUTHORITY DNS 7.3.2512.01". Hide or replace the version string.
    #17
  • !
    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.
