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 2026-12-31 #3

  The registration is valid until 2026-12-31 (70 days).
• i

  No transfer lock

  The domain has no transfer lock (status: active). A registrar lock protects against unauthorized transfers.

  #4

  Delegated to ns.crihan.fr, ns1.univ-lehavre.fr, ns2.univ-lehavre.fr.
• ✓ Parent and zone agree #7

  The parent delegation and the zone's NS records list the same nameservers.
• ✓ Glue present and correct #8

  Glue is published for the nameservers inside the zone: ns1.univ-lehavre.fr, ns2.univ-lehavre.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 3 IPv4 /24s and 2 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
• ✓ All reachable over IPv6 #13

  Every nameserver has an IPv6 address.

  The primary nameserver ns0.univ-lehavre.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.
