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 2027-03-16 #3

  The registration is valid until 2027-03-16 (145 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: 1.si-ns.fr, 2.si-ns.fr.

  #6
• ✓ 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.
• i

  One address family in one network

  all IPv6 addresses are in 2a00:1e70:1234::/48, while the other address family is spread over several networks.

  #10
• i

  All nameservers in one AS

  All nameserver addresses are announced by one network operator (AS50858 (SOLUINFO-ASN - SAS SOLUTIONS INFORMATIQUES SERVICES, 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
• ✓ All reachable over IPv6 #13

  Every nameserver has an IPv6 address.

DS at the parent

DNSKEY in the zone

Checks

• ✓ Signed and validated #27

  The zone is signed, the parent publishes a DS record, and the resolver validates the answers.
• ✓ DS matches a key #28

  The DS record at the parent matches a key in the zone: key tag 1441 (SHA256).
• ✓ Modern algorithms #29

  Key algorithms: ECDSAP256SHA256 (13).
• ✓ Signatures valid until 2026-11-05 #30

  The earliest DNSKEY/SOA signature expires at 2026-11-05 00:00 UTC.
• i

  NSEC

  The zone uses NSEC, so its full contents can be listed by walking the NSEC chain. That is fine unless the names are sensitive.
