    Nameservers not responding
    Nameservers · These addresses did not answer, so resolvers waste time on timeouts: dns10.hichina.com (120.76.107.41): read udp 46.225.38.91:33169->120.76.107.41:53: i/o timeout.

    Serials differ
    SOA · The nameservers serve different versions of the zone: 2016032421 on dns10.hichina.com (139.224.142.111); 2026081813 on dns9.hichina.com (120.76.107.42); 2026082509 on dns10.hichina.com (2408:4009:501::18), dns9.hichina.com (139.224.142.122), dns9.hichina.com (120.76.107.52), dns9.hichina.com (2408:4009:501::17); 2026082616 on dns10.hichina.com (47.118.199.201), dns10.hichina.com (39.96.153.51), dns10.hichina.com (47.118.199.211), dns9.hichina.com (139.224.142.112), dns9.hichina.com (47.118.199.212), dns9.hichina.com (47.118.199.202); 2026082617 on dns10.hichina.com (39.96.153.41), dns10.hichina.com (120.76.107.51), dns9.hichina.com (39.96.153.42), dns9.hichina.com (39.96.153.52); 2026082709 on dns10.hichina.com (139.224.142.121). This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.

    Unusual SOA timers
    SOA · expire 1d is shorter than 7d; secondaries stop answering too soon when the primary is down. Current values: refresh 1h, retry 20m, expire 1d, negative TTL 10m.

    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.
