  • !
    Serials differ
    SOA · The nameservers serve different versions of the zone: 1002974787 on ns1.google.com (216.239.32.10), ns1.google.com (2001:4860:4802:32::a), ns2.google.com (216.239.34.10), ns2.google.com (2001:4860:4802:34::a), ns3.google.com (216.239.36.10), ns3.google.com (2001:4860:4802:36::a); 1003797344 on ns4.google.com (216.239.38.10), ns4.google.com (2001:4860:4802:38::a). This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.

    Unusual SOA timers
    SOA · refresh 15m is outside 20m–1d; retry 15m should be shorter than refresh 15m; expire 30m is shorter than 7d; secondaries stop answering too soon when the primary is down; expire 30m must be longer than refresh + retry; negative caching TTL (minimum) 1m is outside 5m–1d (RFC 2308 recommends 1–3 hours). Current values: refresh 15m, retry 15m, expire 30m, negative TTL 1m.

    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.
