    Serials differ
    SOA · The nameservers serve different versions of the zone: 2026068506 on ns1.insee.fr (194.254.37.129), nsa.perf1.fr (81.92.94.100), nsa.perf1.fr (2a01:c8:100::100), nsb.perf1.com (81.92.95.100), nsb.perf1.com (2a01:c8:101::100), nsc.perf1.com (152.89.172.100), nsc.perf1.com (2a09:35c0:102::100); 2026068507 on ns2.insee.fr (143.196.255.130). This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.

    NSEC3 with extra iterations or salt
    DNSSEC · NSEC3 uses 0 iterations and a 16-byte salt. RFC 9276 recommends 0 iterations and no salt: extra iterations cost resolvers CPU and add no real protection, and some validators treat high counts as insecure.

    Policy: quarantine
    DMARC · DMARC policy is set to 'quarantine'. Consider upgrading to 'reject' for stronger protection once you've verified legitimate emails are passing authentication.

    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: freyja.insee.fr, freyja2.insee.fr, heimdall.insee.fr, heimdall2.insee.fr

    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: dkim (1024 bits). Rotate to a 2048-bit key.

    Not configured
    TLS · MTA-STS is not configured, so other mail servers fall back to unencrypted delivery when TLS fails or is stripped by an attacker. Publish a _mta-sts TXT record and a policy at https://mta-sts.<domain>/.well-known/mta-sts.txt.
