Problems

  • !
    No IPv6
    Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13
  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.aftermarket.pl: "PowerDNS Authoritative Server 4.9.17 (built Aug 5 2026 13:27:37 by root@localhost)"; ns2.aftermarket.pl: "PowerDNS Authoritative Server 4.9.17 (built Aug 5 2026 13:27:37 by root@localhost)". Hide or replace the version string.
    #17
  • !
    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 15s, expire 1d, negative TTL 1h.
    #23
  • !
    NSEC3 with extra iterations or salt
    DNSSEC · NSEC3 uses 1 iteration and a 1-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.
    #31

    DKIM · _domainkey.naturallabs.fr does not exist (SERVFAIL), so no DKIM keys are published. DKIM helps prevent email spoofing. Configure DKIM with your email service provider.
    #7
  • !
    No MX records
