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 2027-09-28 #3
    The registration is valid until 2027-09-28 (341 days).
  • i
    No transfer lock
    The domain has no transfer lock (status: active, auto renew period). 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

  • ✓ 3 nameservers #6
    Delegated to dnssla.univ-toulouse.fr, ns1.uttop.fr, ns2.uttop.fr.
  • ✓ Parent and zone agree #7
    The parent delegation and the zone's NS records list the same nameservers.
  • ✓ 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 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.
    #13

    Software version disclosed
    These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.uttop.fr: "9.18.49-1~deb12u2-Debian"; ns2.uttop.fr: "9.18.49-1~deb12u2-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: dnssla.univ-toulouse.fr (194.57.114.220): 118 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.

    Unusual SOA timers
    retry 1h should be shorter than refresh 1h; expire 1d is shorter than 7d; secondaries stop answering too soon when the primary is down. Current values: refresh 1h, retry 1h, expire 1d, negative TTL 1d.

    Hidden master
    The primary nameserver ns1.enit.fr is not listed as a nameserver: a hidden master that only feeds the public secondaries. That is a common setup; make sure it is not reachable for zone transfers from outside.
