  • 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 2027-01-08 #3
    The registration is valid until 2027-01-08 (78 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: pulsar.univ-valenciennes.fr, titan.univ-valenciennes.fr.

  • !
    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only at the parent: pulsar.univ-valenciennes.fr, titan.univ-valenciennes.fr; only in the zone: proxy1-rech.uphf.fr, pulsar.uphf.fr, squidpumvm.uphf.fr, titan.uphf.fr. proxy1-rech.uphf.fr, pulsar.univ-valenciennes.fr, pulsar.uphf.fr, titan.univ-valenciennes.fr, titan.uphf.fr report NS proxy1-rech.uphf.fr pulsar.uphf.fr squidpumvm.uphf.fr titan.uphf.fr.
    #7
  • ✓ No glue needed #8
    All nameservers are outside the zone, so no glue records are needed.
  • ✓ 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 3 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): 6 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

    Software version disclosed
    These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: proxy1-rech.uphf.fr: "9.20.21-1~deb13u1-Debian"; pulsar.univ-valenciennes.fr: "9.9.5-9+deb8u15-Debian"; pulsar.uphf.fr: "9.9.5-9+deb8u15-Debian"; titan.univ-valenciennes.fr: "9.20.23-1~deb13u1-Debian"; titan.uphf.fr: "9.20.23-1~deb13u1-Debian". Hide or replace the version string.

  • ✗
    Zone transfer allowed
    These nameservers send the complete zone to anyone who asks (AXFR), exposing all host names: pulsar.univ-valenciennes.fr (193.50.192.1): 13464 records; pulsar.uphf.fr (193.50.192.1): 13464 records. Restrict zone transfers to your secondary servers.
    #18
  • ✓ TCP supported #19
    All nameservers answer over TCP.
  • ✓ EDNS supported #20
    All nameservers support EDNS(0).
  • ✓ Public addresses #21
    All nameserver addresses are publicly routable.
