Checks

  • i
    .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.
  • ✓ Expires on 2030-02-17 #3
    The registration is valid until 2030-02-17 (1214 days).
  • i
    No transfer lock
    The domain has no transfer lock (status: active). A registrar lock protects against unauthorized transfers.
    #4
  • ✓ Registry and delegation match #5
    The nameservers registered at the registry are the ones published in DNS.

    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only at the parent: panoramix.rap.prd.fr. dns0.ensad.fr, dns1.ensad.fr report NS dns0.ensad.fr dns1.ensad.fr.

    Glue is published for the nameservers inside the zone: dns0.ensad.fr, dns1.ensad.fr.
  • i
    Could not be checked
    Resolving these nameserver names failed: panoramix.rap.prd.fr (DNS query for panoramix.rap.prd.fr failed: read udp 46.225.38.91:47979->8.8.8.8:53: i/o timeout).
    #9
  • !
    Nameservers in one network
    all IPv4 addresses are in 194.254.227.0/24. 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 (AS2200 (FR-RENATER - Renater, FR): 2 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
  • i
    Partly IPv6
    These nameservers have no IPv6 address: dns0.ensad.fr, dns1.ensad.fr.
