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 2026-12-31 #3
    The registration is valid until 2026-12-31 (70 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: dns.lyon.inserm.fr, ns1.genoscope.cns.fr; only in the zone: ns3.inserm.fr. ns1.inserm.fr, ns2.inserm.fr, ns3.inserm.fr report NS ns1.inserm.fr ns2.inserm.fr ns3.inserm.fr.
    #7
  • ✓ Glue present and correct #8
    Glue is published for the nameservers inside the zone: dns.lyon.inserm.fr, ns1.inserm.fr, ns2.inserm.fr.
  • ✗
    Nameserver names don't resolve
    These nameservers have no A or AAAA record, so they can't be reached (lame delegation): ns1.genoscope.cns.fr.
    #9
  • ✓ Nameservers in different networks #10
    The nameservers are spread over 4 IPv4 /24s and 0 IPv6 /48s.
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS2200 (FR-RENATER - Renater, FR): 4 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: dns.lyon.inserm.fr, ns1.inserm.fr, ns2.inserm.fr, ns3.inserm.fr.
