    .fr is a country-code TLD (ccTLD)
    Country-code TLD: governed by its local registry under national policy, not by an ICANN contract. Registrar accreditation, dispute resolution and RDAP/WHOIS rules are set by the registry.
    #1
  • ✓ TLD delegated and signed #2
    .fr is delegated in the root zone and DNSSEC-signed.

    The registration is valid until 2031-01-28 (1559 days).
  • ✓ Transfer locked #4
    Registry status: client transfer prohibited.
  • ✓ Registry and delegation match #5
    The nameservers registered at the registry are the ones published in DNS.

Checks

  • ✓ 3 nameservers #6
    Delegated to ns1.rs2i.fr, ns2.rs2i.fr, ns3.rs2i.fr.
  • ✓ Parent and zone agree #7
    The parent delegation and the zone's NS records list the same nameservers.
  • ✓ Glue present and correct #8
    Glue is published for the nameservers inside the zone: ns1.rs2i.fr, ns2.rs2i.fr, ns3.rs2i.fr.
  • ✓ All names resolve #9
    Every nameserver name has an address and is not an alias.
  • !
    Nameservers in one network
    all IPv4 addresses are in 185.159.97.0/24. A single network failure takes all nameservers down; RFC 2182 recommends topologically separate networks (anycast setups are an exception).
    #10
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS202604 (NGCLOUD - NG Cloud SAS, FR): 3 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.
    #11
  • i
    All nameserver names under .fr
    All nameserver names are under one TLD, so a problem with that TLD also makes the nameservers unreachable. Some operators use names under two TLDs for extra resilience.
    #12
  • !
    No IPv6
    None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13

    Open recursion
    These nameservers resolve names for anyone, which makes them usable for DNS amplification attacks and cache poisoning: ns1.rs2i.fr (185.159.97.101), ns3.rs2i.fr (185.159.97.101). Disable recursion on authoritative servers.
    #16
  • !
    Software version disclosed
    These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.rs2i.fr: "9.9.4-RedHat-9.9.4-74.el7_6.1"; ns2.rs2i.fr: "9.9.5-9+deb8u6-Debian"; ns3.rs2i.fr: "9.9.4-RedHat-9.9.4-74.el7_6.1". Hide or replace the version string.

  • ✗
    Zone transfer allowed
    These nameservers send the complete zone to anyone who asks (AXFR), exposing all host names: ns1.rs2i.fr (185.159.97.101): 145 records; ns3.rs2i.fr (185.159.97.101): 145 records. Restrict zone transfers to your secondary servers.
    #18
  • ✓ TCP supported #19
    All nameservers answer over TCP.
  • ✓ EDNS supported #20
    All nameservers support EDNS(0).
  • ✓ Public addresses #21
    All nameserver addresses are publicly routable.
