    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only at the parent: byron.ns.cloudflare.com, saanvi.ns.cloudflare.com; only in the zone: dns1.corum.fr, dns2.corum.fr. byron.ns.cloudflare.com, dns1.corum.fr, dns2.corum.fr, saanvi.ns.cloudflare.com report NS dns1.corum.fr dns2.corum.fr.

  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: byron.ns.cloudflare.com: "2026.10.2"; dns1.corum.fr: "2026.10.2"; dns2.corum.fr: "2026.10.2"; saanvi.ns.cloudflare.com: "2026.10.2". Hide or replace the version string.

    Policy: none (monitoring only)
    DMARC · DMARC policy is set to 'none', which only monitors but doesn't protect against spoofing. Consider upgrading to 'quarantine' or ideally 'reject'.

    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.

    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: selector1 (1024 bits). Rotate to a 2048-bit key.
