    Nameservers not responding
    Nameservers · These addresses did not answer, so resolvers waste time on timeouts: ns12.xincache.com (163.177.5.23): read udp 46.225.38.91:35769->163.177.5.23:53: i/o timeout; ns12.xincache.com (129.211.176.239): read udp 46.225.38.91:52447->129.211.176.239:53: i/o timeout.

    Glue differs from the zone
    Delegation · The addresses at the parent (glue) differ from the addresses in the zone: ns11.xincache.com (glue 1.12.0.4, 112.80.181.45, 117.89.178.173, 129.211.176.209, 2402:4e00:1470:2::e, 36.155.149.180, zone 112.80.181.45, 129.211.176.209, 1.12.0.4, 125.94.59.210, 36.155.149.180, 117.89.178.173, 2402:4e00:1730::e, 2402:4e00:1470:2::e); ns12.xincache.com (glue 1.12.0.1, 112.80.181.111, 117.89.178.184, 129.211.176.239, 2402:4e00:111:fff::c, 36.155.149.176, zone 163.177.5.23, 117.89.178.184, 112.80.181.111, 129.211.176.239, 1.12.0.1, 36.155.149.176, 2402:4e00:111:fff::c).

    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns11.xincache.com: "DNSPod AUTHORITY DNS 7.3.2512.01"; ns12.xincache.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.

    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.
