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 2027-05-14 #3
    The registration is valid until 2027-05-14 (204 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.

    2 nameservers
    Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: dns.lyon.inserm.fr, dns1.chu-montpellier.fr.
    #6
  • !
    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only at the parent: dns.lyon.inserm.fr; only in the zone: dns2.chu-montpellier.fr. dns1.chu-montpellier.fr, dns2.chu-montpellier.fr report NS dns1.chu-montpellier.fr dns2.chu-montpellier.fr.
    #7
  • ✓ Glue present and correct #8
    Glue is published for the nameservers inside the zone: dns1.chu-montpellier.fr.
  • ✓ All names resolve #9
    Every nameserver name has an address and is not an alias.
  • ✓ Nameservers in different networks #10
    The nameservers are spread over 2 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): 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.

    Nameservers not responding
    These addresses did not answer, so resolvers waste time on timeouts: dns.lyon.inserm.fr (194.57.163.154): read udp 46.225.38.91:52028->194.57.163.154:53: i/o timeout.

  • ✓ All authoritative #15
    Every responding nameserver answers authoritatively for the zone.
  • ✓ No recursion #16
    The nameservers do not answer recursive queries for other domains.
  • ✓ No version disclosed #17
    The nameservers don't reveal their software version.
  • ✓ 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: dns1.chu-montpellier.fr (195.83.227.126): dial tcp 195.83.227.126:53: i/o timeout; dns2.chu-montpellier.fr (195.83.227.127): dial tcp 195.83.227.127:53: i/o timeout.
    #19
  • ✓ EDNS supported #20
    All nameservers support EDNS(0).
  • ✓ Public addresses #21
    All nameserver addresses are publicly routable.
