.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 2029-01-07 #3

The registration is valid until 2029-01-07 (807 days).
✓ Transfer locked #4

Registry status: client transfer prohibited.
✓ 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: ns1.retzien.net, ns2.retzien.net.

#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.
✓ 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 (AS12322 (PROXAD - Free SAS, FR): 2 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 .net

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

Identifying string disclosed

These nameservers answer version queries with a string that is not a version number: ns1.retzien.net: "unknown"; ns2.retzien.net: "unknown".

#17
✓ Zone transfers refused #18

No nameserver allows a zone transfer to the public.
✓ 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.

Wildcard record

A random name under the zone resolves, so there is a wildcard (*) record. Typos and non-existent hosts resolve too, which can confuse mail and certificate checks.
