  • 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 2027-01-29 #3
    The registration is valid until 2027-01-29 (99 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: ns.ac-amiens.fr, orion.utc.fr; only in the zone: dns-srv1.ac-amiens.fr, dns1.utc.fr. dns-srv1.ac-amiens.fr, dns1.utc.fr, mars.ac-creteil.fr, ns.ac-amiens.fr, orion.utc.fr report NS dns-srv1.ac-amiens.fr dns1.utc.fr mars.ac-creteil.fr.

    Glue differs from the zone
    The addresses at the parent (glue) differ from the addresses in the zone: ns.ac-amiens.fr (glue 194.199.46.3, zone 195.221.153.10). Update the glue at your registrar.
    #8
  • ✓ All names resolve #9
    Every nameserver name has an address and is not an alias.
  • i
    One address family in one network
    all IPv6 addresses are in 2001:660:4201::/48, while the other address family is spread over several networks.
    #10
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS2200 (FR-RENATER - Renater, FR): 7 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-srv1.ac-amiens.fr, mars.ac-creteil.fr, ns.ac-amiens.fr.

    #17
  • ✓ Zone transfers refused #18
    No nameserver allows a zone transfer to the public.
  • ✗
    No DNS over TCP
    DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: dns-srv1.ac-amiens.fr (195.221.153.10): dial tcp 195.221.153.10:53: i/o timeout; ns.ac-amiens.fr (195.221.153.10): dial tcp 195.221.153.10:53: i/o timeout.
    #19
  • ✓ EDNS supported #20
    All nameservers support EDNS(0).
  • ✓ Public addresses #21
    All nameserver addresses are publicly routable.
