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 2027-07-02 #3
    The registration is valid until 2027-07-02 (253 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.

Checks

  • i
    2 nameservers
    Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns.ensiie.fr, ns2.ensiie.fr.
    #6
  • !
    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only in the zone: asimov.cnam.fr, hyperion2.univ-evry.fr. hyperion2.univ-evry.fr, ns.ensiie.fr, ns2.ensiie.fr report NS asimov.cnam.fr hyperion2.univ-evry.fr ns.ensiie.fr ns2.ensiie.fr.
    #7
  • ✓ Glue present and correct #8
    Glue is published for the nameservers inside the zone: ns.ensiie.fr, ns2.ensiie.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 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
  • !
    No IPv6
    None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13

Checks

  • ✓ All respond #14
    All 4 nameserver addresses answered.
  • ✗
    Lame delegation
    These nameservers don't answer authoritatively for the zone, so resolvers ignore them: asimov.cnam.fr (163.173.128.6): REFUSED, authoritative=false.
    #15
  • ✓ No recursion #16
    The nameservers do not answer recursive queries for other domains.
  • i
    Identifying string disclosed
    These nameservers answer version queries with a string that is not a version number: ns.ensiie.fr: "dnssrv"; ns2.ensiie.fr: "dnssrv".
    #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: asimov.cnam.fr (163.173.128.6): .
    #19
  • ✓ EDNS supported #20
    All nameservers support EDNS(0).
  • ✓ Public addresses #21
    All nameserver addresses are publicly routable.
